My one ? is you have ladder bar's or leaf springs if you have leaf spring you have a good choice of rear ends out there.

I know from 1964-70 used the same rear end cus they are all 6 lug one difference you you have ladder bars or leaf springs.that on outer housing now the rears will be different.But you find one with a auto th350 and 400 its pretty close to the 3.77 or 3.55.

Any thing new after 1998 and up had really bad casting on there Gears and bearings seen a ton of 1999--2009 Chevy rear shear teeth or crack spider gears Some tell me its the oil additive they used and the weight there where using
