Fox Body Rear End Swap Problems
Hey guys, I have a 1991 Mustang GT that I recently upgraded the rear end in. The rear end that was in it was the stock 8.8 rear end that had 2:73 gears (hence the upgrade). It had drum brakes as well.
This is where things get a little complicated. I had bought a parts car awhile back, a 1988 Mustang GT. The reason for buying it was because it had a 8.8 rear end in it with 3:73 gears and the price was reasonable to buy the rest of the car as well. So I bought the car and brought it home and started stripping parts off of it.
Just recently I finally got around to installing the rear end that was in that parts car into my actual driver (the 91 GT). The rear end that came out of the parts car had disc brakes instead of drum brakes, but still had 4-lug axles.
The rear end is currently installed in my car and it functions, but there are a few problems. First of all, the quad shocks that were the stock ones that go along with the stock rear end are no longer usable. We drove it down off the ramps and noticed the back end sat up real high and was as stiff as a board, so we got it back up in the air and found that the quad shocks were maxed out, so we took them out so that the rear suspension could actually function.
However, now that the quad shocks are out, the tires ( 17" rims, 255/45's) now rub going down the road quite a bit. We've been looking at it and it seems as though the rear end we put in is a little bit wider than the stock one that was in it. We've been thinking that the rear end with the 3:73's was out of a SN95 Mustang, which is why it had disc brakes, but then why would it still have 4 lug axles?
Another issue we have is that the e-brake cables don't reach quite far enough in this new rear end, they seem to be an inch or so too short. So do you guys have any suggestions on what e-brake cables would work?
So if any of you guys can shed some light on my problems that would be great. I basically just need to know what to do about the rubbing issue due to the wider rear end. I think it could be solved with new quad shocks, but I don't know which ones to buy due to not knowing what the rear end I have is originally out of, or if they even make quad shocks that would work. The issue seems to be where the quad shock bolts up on the rear end itself. On the stock fox body rear end the bracket was straight up and down, on this new one the bracket is at a bit of an angle, which is why the quad shocks don't work anymore.
Thanks in advance for taking your time to read this and help me out, I appreciate it greatly.
(ps. do any of you know right off hand which speedometer gear I need for the 3:73 gears so that my speedo is accurate?)
