So I have the 60, but all I'm using is the housing. I'm upgrading to a 35 spline suregrip posi along with the new 35 spine shafts/green bearings from Dr. Diff. So it certainly wont be stock. I'll be $1600 in it with all the parts. Even less if the 60 I have is 4.10. I gotta crack it open, because if it is then I can use those gears again.

That's the exact route I went. Got the rearend out of a mid-70's F250 at a pick-n-pull w/ a 4.10 gear, Trackloc, and 1350 yoke. After selling the Trackloc, I swapped in a powrlock, added some Mopar housing ends, and a set of Dutchman axles with 5/8" studs (all parts from Dr. Diff).

You won't regret it! What is the wall thickness of the axle tubes in yours? Mine were 5/16"!!
