Rear end options for 1960

[demian5]

Hi - Im usually on the 67-72 board.

I am about to start helping a friend with a 60 c10 that is kind of half-ass done.

Its got stock 6-lug front end (that we will convert to discs and lowered spindles). And 5-lug rear that has the wheels sticking out like a 70s disco van.

What year span of rear ends would bolt in? Which makes me wonder if there is going to be Frankenstein stuff for whatever rear end is in there...

I'm not even sure if its a 350 or PG trans yet so that another story (gearing). Its a V8 so probably a 350.

Thanks in advance.

A '63 to early '70 truck 12 bolt will be the same width as the original Eaton HO32/33. The '71-'82 truck 12 bolts will be 1.5" wider as well as the '79-'87 10 bolts. Regardless of which differential you choose the trailing arm mounts will need to be moved to fit properly to the '60 trailing arms. Plus you will need a panhard bar mount. The '60-'64 C10's and '60 to '72(?) C20's with the Eaton HO52/72 will have the same passenger side axle tube mount for the panhard bar. If you find that you need a set of trailing arm mounts, I do make those along with all of my other products.

Many 1960 GMC's came with a Dana 44 rear axle, my truck included. When I added disc brakes to the front, I had the rear axles redrilled to 5 lug.
