So, does anyone here know anything about replacing ring/pinion & differentials? I have embarked on my first attempt (solo, too), & am Installing an Auburn Ected LS/Locking diff., with 4.56 gears in the rear of my ZR2.

The problem that I am encountering is that I don't have any .005" shims in my Genuine(Motive) Gear install kit. Right now, the diff backlash is at .0055", & the specs are for .006-.010". If I add the thinnest shim in the kit (.010") to the right side, & remove .010" from the left side, then I end up with .012-.0125" backlash(out of specs!). Are there .005" shims available? Would .0055" lash hurt my gears?

Please help, if you have experience in this area! Thanks!
