8 3/4 pinion depth

If I were home I could give you that info. The depth setting gauge kit I bought has
very helpful instructions that came with it. They give you a pinion depth for most factory gear sets. If you can wait till the weekend when I'm home I'll be able to help you.

Who's kit did you get? I bought a Summit & I think I could get closer with a tape measure!!
I went ahead & mocked it up w/original shim-0.031". The original pinion was marked (-1), so I used original shim,thinking nominal PD was 2.765 & new PD @ 2.769, that I would end up 4-5 thousandths deeper. Perfect for a drag style R&P setup!
I agree on the 0.009 BL, it has more contact area..........TKS, Mike
