C-20 rearend ID

What rear-ends were available on the 3/4T trucks? I know the DANA 60 was, but was there another one available? I don't think mine is a DANA and I would like to swap in some taller gears, because the PO put in some insanely low gears.

Thanks in advance.

Re: C-20 rearend ID

Your truck more than likely has a Eaton HO-52 rear end in it. As far as putting in higher gears, you'd be better off to get a different axle. The Eatons are obsolete, and the highest gears you can get for them are 4.10 ratio.
