'69 C10 - Black on Black

[MDPotter]

We got the rear gear/limited slip swap done last night. Manufacturing tolerances must have gotten tighter in the last 50 years because we ended up with no shims on the pinion and only a few small shims on the carrier compared to about 2-3X the shims that were on the carrier and pinion we pulled out. We got the lash in spec (.090), a good pattern, and the correct preload on the pinion. We just have to close it up and fill it and it'll finally be back on it wheels again.

This has been a learning experience for us - it's something that I had no idea how to do and now it's so simple. It takes a few special tools (and a lot of leverage to crush the sleeve on the pinion) but has been fun and it's a skill that we will use again for sure on other trucks.
