pinion depth, how close does it have to be

perfacar said
is there a pinion depth on the gear??

There is, 2.771 I think. Lemme go look

2.770

Ended up at 41 thou shim. 42 was too deep and 40 was too shallow. Not much room for error.

I just tried different shims until I got there. No depth gauge, just several hours of work
