Coils or leafs? Chevys were standard with coils, but leafs were available as an option. Once you have that answer, shop your local junk yards for the rear from a 1/2-ton 67-70 Chevy or GMC that came with a V-8 and automatic.

My '72 with a factory 350/350 setup has 3.42 or something close.

If you can find one with the same spring type you should be able to just bolt and unbolt to install it.

It's true. I really don't do anything but browse the Internet looking for trouble...
