1/2 ton to 3/4 ???????

[1969 GMC]

If you're gonna be towing, I'd upgrade to disc brakes in the front.

And fyi, the 3/4 ton and 1/2 ton front axles are the same thing, with different #'s of lug nuts. Like 69k10step said, the rear axle is the only one that's different.

i'd try to find a mid 70's K20 and swap that stuff over. unless that '68 is totally trashed, you could sell it and make some $$ back.
