bringing this thread back. it's not too old. :) to anyone who's running either of the DrDiff 13" fronts. with what K-member and sway bar? still loving them? any problems?
First off, I'm running the Hotchkis TVS. The Hotchkis UCA's have a big curve in them (some other aftermarket tubular UCA's have them too) that cause interference way before full-lock, so the calipers have to be front mounted. Looking at it, there's no way anyone will be able to use any sway bar besides Hotchkis's as it's the only one that mounts inboard on the LCA. Also, an 18" wheel is practically required. I tried fitting a 17" Bullet Mustang wheel and it rubbed on the inner wheel. I'm not sure how the '73-76 cars are, but that's for the '66-72 cars. I hope that's of some help...
