Are your front wheels 15" x 6" ? I've gor a '68 Valiant with the same wheels (except painted) and same exact tires (215/60R15 BFG Radial T/A). My right front rubs on the front lower corner of the fender on sharp turns, and I don't have a motor in the car yet. Just wondering if you've got the same issue or not. I did the '73 up disc brake swap with the '73 up upper control arms. I'm wondering if I switch to the tubular arms if that may help gain some clearance (different caster angle I believe). I really don't want to switch to a 205/65R15, but you can see where mine rub in the pic below. I think the 215/60R15 fill the wheel well nicely though. Your brakes look way better than my stock pieces. Looking great... keep up the awesome work!
