Most any old dodge Dana 60 out of a 72-93 3/4 ton truck will be good. Most had 4.10’s.

I have a Dana 60 HD with a set of 4.10’s and a sure grip unit that needs to be rebuilt (sure grip unit itself) for sale if your interested. The bare housing was stripped and painted with Nason Farm&Machine gloss black out of a spray gun. I was gonna use it in my power wagon.
I’m in Hollister.

Toby Lavender, Lavender Brothers in Salinas can build it for ya.
