6.1 Hemi 69 Barracuda Fastback Father Son Project

I don't think that's going to be an easy fix for you. C-body rotors use different outer wheel bearings than 73+ A body rotors. They use a different caliper as well, one that can work with the 1.25" thick rotors C-body rotors. And those calipers have a different bolt spacing than the A/B/E/F/M/J calipers do.
Well crap... then .300" is all that I'll get out of shaving the wheels.

Although, just now, when I looked up 17x8 mopar rallye wheels online, they show 4.5" backspace not 4.25"
I've always though they were 4.25" BS, 0 offset, but YO, Jegs, Classic Industries, and others say they are 4.5" BS, -6mm offset... Wonder if they changed or if they were always 4.5"?
Oh well, I will measure what mine are when I get them back from the machine shop next week.
If they were 4.5" BS and I gain another .300" I'll have 4.8" BS... hmmm just numbers. In the end, what matters is what tire will fit without rubbing... 235/45-17 maybe IDK but I'll find out "¯\_(ツ)_/¯"
