The determining factor will be rearend width. I have a 72 rearend, which is wider than the 67-70 rearends. That's going to change your backspace numbers. Also, for what it's worth, the 5.25" backspacing is still a bit too much for a stock stepside bed. 5" bs would've been ideal, but hard to come by in a one-piece wheel.

Again, as SCOTI said, measuring what you have is the best way to know what will and won't fit.

Your truck & '1971_c10' truck were the 1st two I thought of when I opened this thread. Thanks for reinforcing the need to check your personal set-up vs what another truck might have. It can be a frustrating & expensive mistake.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
