50 resto has a kit, you need new clutch pack its kind of hard to find on the site either that or it was just me, that includes everything to do the job. also americanmuscle.com has a gear instalationn kit you should probably get that it comes with your bearings just to do it while youre in there

The directions come with the ford kit. It's not hard.

Jack the car up and support it with jack stands on the axle. You start by removing the diff cover, drain the fluid. Take the small bolt off the pin and slide the pin that goes through the middle of the diff out. Push the wheels/axles in towards the center of the car. This will expose the C-clips. Take the C-clips off. Drive the S-spring out with the wooden side of a hammer. Now you slide one axle back in and put the car in gear. Turn the axle slowly and the planetary gears will spin out. You can now take the diff gears out with the steels, clutches, and shims. Measure the clutch pack with a micrometer. Soak your new clutch packs in gear oil for an hour. Then stack the clutches with alternating steels (this way you can fit 4 clutches in there instead of the stock packing that goes clutch-steel-steel-clutch) Reuse the one clutch that is at the back of the diff and turn it over (the rebuilds only come with 3 clutches). Measure the new clutch pack and put use a shim that will bring the total width up to the same width as the clutch pack when you disassembled it. SHould be around 0.030". Reassembly is the opposite of dissasembly. Getting the s-spring back in is the hardest part. Use two worm clamps to squeeze the spring down and slide it in, then take the worm clamps off and pull them out with a pair of vise grips. Refill with 80w-90. Oh yeah, don't forget the friction modifier.
