Tools:
2 Tubes of Urethane adhesive
Image

I got mine from a local Glaser for $20.00 a piece.

Caulk Gun
Torx Socket set
Metric Socket set
Phillips/Flat head screw driver

Step I:
Start by removing the cover on the seat belt loop anchor and unscrew the coat hanger with a Phillips screw driver.

Image


Once you've popped off the cover on the seat belt anchor you will reveal a torx bit fastener that also needs to be removed.

Image


Once you've removed the belt anchor go ahead an remove the Christmas tree fastener, aka ribbed shank, that was sitting underneath it using a flat head screw driver, be careful not to damage your plastic interior as you can tell i take great care in mine.

Image


Now proceed to remove the panel from the car, I find that it works best to pull from the door opening and make my way back towards the rear windshield, I believe there are only three ribbed shanks holding it to the inside wall. When removing be careful not to damage the defrost connector.
Image


Sometimes the ribbed shanks like to stay put on the car
Image


You're going to have to remove them and if you look at the picture they have a lip under the head
Image


which goes here on the panel you just removed.
Image


and here is a picture of it installed on the panel.
Image


this will make the re-installation much easier when you're putting the plastic paneling back in its place.

Step II:

You are now presented with the hex nuts that are holding down the C-Pillar to the vehicle, there are five in total. I pointed them out in the pictures below.

Image


Image


Go ahead and remove these you will notice this on all the nuts

Image


that's just urethane adhesive that was applied to the nuts. Go ahead and clean it off the nut, try to get it as clean as possible. Reason being when putting the nuts back you will need to reapply some urethane adhesive to the nut before installing them and your going to want a clean surface for the adhesive to adhere to.

The next step is to remove the exterior gasket.

Remove these 5 pins using a flat head screw driver popping them off of the door jam, try to keep them in the gasket so they don't get lost.

Image


You're than going to pull it out all the way towards the kick panel up front. It should come out pretty easily.

Image


Then do the same with the inside gasket

Image


Image


Now you have revealed the sheet metal bracket that holds both gaskets to the car. You will notice there are torx bit screws holding it to the car.

Image


Image


I like to remove at least the first five starting from the rear of the car towards the front.

Once you've removed the fasteners, pull down the sheet metal bracket trying not to bend it as pictured below.

Image


The previous owner of this vehicle apparently had to access this area in the past and due to it being bent when pulled it will always fold in that area.

If this happens to you it is not that big of deal just don't go to crazy pulling it down. You want to pull it down far enough to be able to see and remove this Phillips screw that's hiding under it and is also holding the A pillar to the car.

Image


There are several, you want to remove the one that is closest to the C-pillar which is the one i circled above.

Once you have removed the screw you will notice the A-pillar is loose where it joins the C-pillar. Go ahead and pull the C-pillar loose from the car starting at the top edge where it meets the rear windshield. You will notice that it is still attached to the car where it meets the A-pillar.

Go ahead and lift the A-pillar from the car while holding the A-pillar in position take the C-pillar and pull it up and then down to unhook it from the A-pillar.

<pic will be added l8r>

Once the C-pillar is removed you'll be left with the 1/4 window.

Image


You will notice underneath the C-pillar there is no clear coat, unfortunately the Mach 1 C-pillar swoops in a little closer to the car and some of this unfinished paint will be visible.

Image


Its actually not that bad depending on how anal you are :).

Also you will need to remove the molding that sits below the 1/4 window, simply jut pull up on it and there are three clips that keep it fastened to the sheet metal.

<pic will b added l8r>

Now make you're way back inside and there will be four 7mm nuts holding the glass to the body. Go ahead an remove these.

Image


After they have been removed go ahead and begin to pry the window off of the car starting from the top of the glass and pulling toward you. It will take a little bit of effort depending on if its a hot day or a cold day. Its easier to remove on a hot day but makes more of a mess.

Step III:

Your going to have to remove all of the old adhesive off of the body of the vehicle, its actually pretty easy. If you take a good chunk of it off of the car and then use that piece of urethane to remove the reaming adhesive from the car. The adhesive sticks to itself better than it does to the metal so by pressing what you have in your hand into whats on the car it will lift and remove the urethane clean off the car. Just repeat this process until its pretty darn clean. I also did this on a hot day which helps greatly if using this method.

If your not having luck with the method above than you can either A) use a blow dryer to heat it up and try it or B) use a gasket scraper to clean it off of the car being careful not to scratch the paint or C) combine methods A and B.

Below is an example of how not to apply urethane adhesive to the vehicle, (I thought I could pull this off before going to school and ended up rushing to get it on and make it to class on time.) This will cause unwanted wind noise and not so good for rainy days.

Image


Image


Image


Here is the proper way of applying the adhesive, you want a nice thick and tall bead on both mating faces.

Image


Image


Image


To back track a little bit you'll want to pull the metal lid of off the bottom of the urethane tube to reveal the plastic cup in which the caulk gun is going to push into and expel the adhesive from the tube. Unscrew the top of the tube and pop a hole in the sheet metal cover on the top portion to allow the adhesive to come out. Then cut the tip of the nose off of the plastic cone and thread it back onto the tube. Load it into the caulk gun and go to town.

Depending on what type of caulk gun you're using it might take ALOT of effort to get the adhesive to come out of the tube. I had a really cheap and crappy caulk gun which required an immense force to squeeze the trigger. I ended up inserting a 3/8" extension into the trigger folding the edges over the extension to encapsulate it and then wrapped it in electrical tape to keep it from flying out of the trigger. By doing this I gave myself more leverage which made squeezing the caulk guns trigger much much easier.

<pic will b inserted l8r>

After you have laid down the adhesive onto the both surfaces go ahead and place the mach 1 window where the GT window was being careful not to make a mess with the adhesive. Easiest way is to line up the glass is to use the two left holes on the body and then the tow right ones, because the right holes are slotted they have more play than the left ones. Push the window down firmly into place and fasten it to the car. You might get some excess adhesive on the inside of the glass you can either cut it off or leave it.

Then re-installation is the reverse of the removal except for the fact that you will be installing the Mach 1 pillars in place of the GT ones.

Also if the C-pillar gasket material doesn't come with you're mach 1 pillars here is a pic on how I re-used my GT gaskets to go onto the Mach 1 Pillars.

<pic will b added l8r>

Also don't forget to put some urethane adhesive on the nuts holding the C-pillar.

sorry to sound stupid but what is the difference Ive owned a Gt and a mach and never noticed it
 
#10 ·
I dont see the difference can you post a pic to show the difference
 
#13 ·
ohh okay so its the angle by the glass pretty much?
 
#16 ·
Yep, same on bullitt ad Mach, most people don't know there is a difference.

great write up man, reps.

Hate to tell you this but you made this alot harder than you had too.. The windows dont need to come out,and the urethane you used is incorrect so next time that window gets smashed the urethane will be rock hard and your gonna have to use a knife to cut it all out. You should of used Butyl tape, it's whats on there originally and thats why it came off very easy once you had a ball of it. Same with that bead you can get tips for that tube and itll make your bead seat alot better and not have any squeeze out because you gobbed it on.


Another thing if your gonna use that urethane please your a primer to help it stick, its not gonna be the greatest hold sticking to clear coat. Also sticking that tube into a tub of hot water allows you to squeeze it out easier if you have to use a manual gun.

LOL...yea..... it doesn't.... but if you leave the GT glass with the Mach 1 Pillars it looks absolutely retarded because the design on the glass follows the curves to their corresponding pillars.

the urethane you used is incorrect so next time that window gets smashed the urethane will be rock hard and your gonna have to use a knife to cut it all out. You should of used Butyl tape, it's whats on there originally and thats why it came off very easy once you had a ball of it.

Don't know where you live but no one smashes 1/4 windows around hear....maybe driver or passenger side windows. Not too worried about it. If the glass is smashed its going to suck to remove regardless what you use.

It's what I used the first time i did the swap, it came off really easy when i redid the windows. (not the side pictured,... the passenger side came out pretty good)

Honestly I went to the Glaser and told him what it was for and that's what he recommended. If you actually look up the adhesive i used one of its selling points is adhering 1/4 windows.

If you have ever removed that 1/4 window from a factory car they also "gobb" it on, you want a nice seal to keep the weather out, especially considering the tolerances on these parts are huge you need to be able to accommodate for that.

Another thing if your gonna use that urethane please your a primer to help it stick, its not gonna be the greatest hold sticking to clear coat.
Please read what is directly on the tube, its the first picture in my write up.

Again....if you have ever removed the 1/4 window from a mustang you will notice there is no clear coat on the paint beneath the C-pillar due to the fact that any adhesive weather it be Butyl or urethane, ....hell in some cases even super glue need a rough surface to help to adhere to. I also have a picture in the write up talking about the non clear coated, rough, dirty, nasty, non shiny, mineral gray surface

Also sticking that tube into a tub of hot water allows you to squeeze it out easier if you have to use a manual gun.
Possibly the most useful part of the comment, thanks for the tip.

Again, I've been in Autobody for 4yrs now with 1 left for my journeyman's ticket. I've probably cut and replaced more windows than you've ever imagine.

They also have never gobbed it on from the factory? It a clean bead with the seams meeting at the bottom with the urethane being blended into the seal above it to make it clean/waterproof.

Hate to burst your bubble but when i see jobs like this go smooth and than someone hacks together the very end its retarted.

There is also a reason why you could pull it off by hand LOLOLOL. Try that with your current setup and let me know how many shards of glass you get in your hands.

One more thing, did you know that both the glass and body take different primers? Probably not.

Your mother must be so proud, im glad you have bragging rights. The guy who gave me instructions on how i should do it at home has been doing it long before you were born whats your point?

Are you asking a question or making a statement? Unless mine were replaced before i bought the vehicle mine was a globby mess and i never had leaks.

Hate to burst your bubble but when i see jobs like this go smooth and than someone hacks together the very end its retarted.
I still don't see where i hacked it? Because its not a pretty little bead? As long as its doing its job and cant be seen who the **** cares really? There's absolutely no leaks, to me that is success your just trying to justify yourself or your just a real DB.

There is also a reason why you could pull it off by hand LOLOLOL. Try that with your current setup and let me know how many shards of glass you get in your hands.
Not exactly sure what your trying to say in the first sentence but that's cool.
I used this same adhesive before and it came off just as easy as what ever was on it before i laid my hands on it. If my window breaks I'll have the insurance company handle it and therefore a body shop will take care of it in which there will be no glass in my hands.

One more thing, did you know that both the glass and body take different primers? Probably not.
yes i did there is also primer for plastics whats your point? its a primer-less adhesive

dude i really don't want to continue this escapade but you came in here criticizing every little thing. It'd be one thing if you actually tried giving me some pointers instead of coming off as a real dick head.

Does anyone know if the glass from the 94-98 cars are the same or at least closeer to the bullitt/mach then the GT? I ask because I found a good deal on the pillars without the glass and I have glass from the 94-98 because I was planning to try and use those C-pillars on my car before I found this deal. Also can you please include the other pics you left out of the original post? Hopefully soon I'll be diving into this project and I would like every bit of info possible.
 
#28 ·
I would like to know this too. It looks to me that the 99-04 glass is actually the same as the 94-98 glass, so if it is (can someone confirm this), then I won't remove the glass . I want to try and install the 94-98 C-pillar sail panels onto my 2000 - they look very similar to the Mach 1/Bullitt C-pillar sail panels, for a lot less $.
 
#35 ·
Looks great man, I never noticed the difference before, but now that I know they are quite a bit different. Great job!

Its also cool to know my c-pillars are similar to the mach1's :)
 
#36 ·
Nice write up, just purchased a set of Bullitt c pillars and glass, pretty excited!
 
#37 ·
Just a Picture of a Black car with the gap of unfinished paint from installing these. I think anyone purchasing these should know about. It is unfinished primer, no paint and no clear.
At the back of the panel has the most showing 1"+. For a temp fix till i get my whole car painted i think I'm going to touch it up, repair it myself.

1"+ inch shows at back, at least 1/4" shows the whole length form the window back.

Hope this helps anyone doing this.
 
#38 ·
Ouch. That is exactly what I wanted to know. There is another user on here who said that there was paint underneath however your pics clearly show otherwise.

I am wondering why some cars would have paint there and others wouldn't. Strange. Unless the stock sail panel rubbed the paint off over the years of vibrations?
 
#41 ·
I'm really not sure about the 94-98 they look the same but to me they also look different then the bullitt/mach 1. I paid $180 for my set with glass, then $100 to have them repainted due to chips, broke corner. Now i got to fix the rear quarter panel. so now I'm gonna have around $400+ into this mod. If i have to take to body shop its gonna be more then that. Subtle mod, but i think its worth it. There is a mach 1 set on corral right now for sale. Here is a picture with the panel off. So you can see how they just didn't paint it. I forgot to take on of the panels next to each other. I already have it masked off, primed i have to block sand it later, maybe prime again depends. The ridge is pretty big. I even wet sanded with 1500 to knock it down before i primed.

Primer showing!
