I have all the parts needed to rebuild a GM 7-5/8" rear axle. The parts will fit all F-body rear axles and all mid-size trucks (S10s and Blazers) from '90 until GM killed off the model lines. I worked at the axle plant on Delavan Ave. in the Quality Dept. and was going to used these parts to rebuild the rear axle on a '90 TransAm, but ended up buying a whole new rear end. The gear set is the best quality we were putting out at that time. I have a 3.42 ratio gear set, an Auburn L/S diff and all the shims, spacers, bearings/races, pinion crush sleeves and nuts, etc., that you would need to rebuild a tired F-body rear. The only parts I can’t find are the crosspin lock screw for the diff and the races for the diff bearings. You can get these parts from GM for a few bucks. Anyone who is seriously interested for getting these parts FREE pm me and we can set up a pickup date/time. These parts have not been used!
