On my 67 Barracuda I still get some rubbing on the right front fender when backing up. Do you have any rubbing issues when turning? 15x6 steelies in front on mine. Going to go to the 17 x 7 enki copies.
After changing to a TVS kit no more rubbing. The strut bar bushing was toast allowing the wheel to move forward when backing up and touching the fender.
