This may be a dumb question but better to ask first. My D60 has studs on the pass. side coming out of the diff instead of the factory bolts. I will be using shims on the axle. My springs already have a small shim installed on the springs, no clue what degree but its nothing big. Ive always heard on the factory bolts, that to use shims, youll need 3 shims, 2 for under the springs, and 1 to go over the pass. spring to even out the spring plate so the bolts sit flat... My question is, do i still need 3 shims on my 60 while using studs instead of bolts?
