12 bolt gear setup pattern
Hey folks, thought I would post these here to get a second(or eighth) opinion on this pattern before I disassemble and reassemble for good. I think it looks pretty good, but since this is my first time, it's best to verify. Thoughts?
Details:
69 Camaro 12 bolt
3:73 Richmond gears
.030" shim on the pinion
Trutrac
Generic Summit axles

It's very close and I would consider it runnable. If you want to try one move a. 032 shim could get it a touch closed. I've set up one 12 bolt but have studied patterns for years so take it for what it's worth. For pro opinion post on chevelles.com. Big gear head is super helpful with patterns.

I'm in the same boat ...not a pro but had mine done and the pattern was a touch "tighter" otherwise I'd say run it .... Part of the reason for a little tighter is for if / when things shift and break in the pattern will open up

I'd say your really close, after doing this check the backlash and see what it is. Looking good though.

Backlash is a touch under .012", which is on the high side of the spec
