I want to swap my 3.08's for 3.73's. The car is an 86' GT with 120,000 miles on it. I have a shop that will do the basic labor I will provide the parts. What do I need to order to do this right ? He said something about rebuilding something so the rear doesn't whine do to the high milage on the car. What is he talking about ?

The basic parts to buy are the ring/pinion of coarse.
A crush sleeve and side shims, 3 qts gear lube and friction modifier are a must.
Yes, you can re-build the posi unit, and buy pinion bearings/seal,
Inner/outer axle bearings/seals.
Its all in how much money you want to spend now.
If the rearend is quiet now then it should be quiet after the gear installation.

Yeah I just put my 3.73s in about 4 months ago. All my bearings checked good so I just reused them. I bought a kit that had pinionshims, side shims, seal and rear gasket from year one was only like $28. I also used solid spacer for my pinion but I do mine myself. It take a little fiddling to get right. I should have rebuilt posi, with many mile would be a good idea, I wish I would have done mine while I had it out.
