WTB 12-bolt or 9" rear end, 67 camaro

[arue333]

Looking for a rear end for my 67 camaro, 12 bolt or 9",
9", looking for 31-spline axles, chevy bolt pattern, trutrack possi, and disk brakes. Or as close as you can get to it?

12 bolt, c-clip eliminators, disk brakes and trutrack possi.

My 67' is powered by a 96 LT1 with a T56 6 speed. Have any ideas of what gear ratio is needed for that setup?

Rear tires are still undecided but going with 18" rims and a G-link suspension out back.

Any help is greatly appreciated,
