Wheel/tire fitment help

[bdepedro]

A buddy of mine is working on a '70 Mach1 and is trying to figure out if the wheel/tire combo he wants will fit under stock wheel wells. He's looking at 235/60R15 on 7" wheels on the front and 275/60R15 on 8" wheels out back. I think he's planning on old school Crager SS wheels but not sure what backspacing he's thinking. Can anybody tell me if these will fit without rubbing? Thanks!

Backspace is critical. But size matters, and I don't see how a 275 will fit on the back no matter what offset you have-

Saw another thread on wheel size with a link to Dodgestang's chart which shows a couple of 275 configurations that may work. I sent this to my friend. Looks like a list of specs from people who have these combos on their '69-70s that work.
