Fairlane fiberglass extra-wide (+ 2 1/2) rear fenders seem to swallow my cardboard mockup tire. It's an M&H P390-45x15 on a 15 x 12 Weld 96 wheel with 3 1/2" backspacing.
C4 front calipers adapted to the 9" rear. At the time, I did not realize that the fronts have a 2 1/8" piston and the rears have a 1 5/8" piston. Had I known, I would have bought a set of rears. I chose not to because I already had the fronts and used those for mockup.
