Thanks in adavance for any help. This is my problem, I had a shop install a set of FMS 3.73 gears, but the gears that were in my rear end were precision gears, which uses a different set up. This shop used the same shim that was in the pinion of the precision pinion gear for my FMS gears and they haul like a Wolf on heat, I took it back and the guy who put them on claims that he did everything right, so we argue for a while, and he won't fix them, well I din't pay him either. So can anybody tell me what is the shim size that comes in the 8.8 rear ends from the factory, when I check the one that is on now is .032" the pattern shows that the pinion is to close to the gears, at the hill of the gears. If I can get the right shim, I'll do it myself. Thanks.
