Hi everyone. I just picked up a set of Gladiator non-rubicon axles. I am regearing them to 4.88 and I just finished the front. Now the rear (m220) stock pinion has a marking of 0.55 with a shim thickness of .0490" and the new pinion has 0.13 on it. I don't see the +- markings on these like there were on the front so im lost. What do these numbers on the pinions mean? how do I set up my shim stack for them?
