Front End Problems
They swaybar tabs were probably moved inboard to try and make the '72-down K-member and swaybar work w/'73-up discs. Or they just swapped the spindle/disc/upper control arm onto the early lower control arms. Same problem will occur- the caliper smacks into the tabs and/or bar. The least aggravating solution is to swap the K-member, suspension, and braking system from a single donor car, preferably a '73 up V-8 w/ the dropped center link. Rebuild it using Moog parts; offset bushings in the upper arms (set them up so the forward bushing's hole is to the ball joint, the rear bushing is placed w/ the hole away from the ball joint- this lets the steering react to the stronger bite of today's radials) and the 'improved design' strut rod bushings. Grab a set of '74 C-body tie rod ends, weld the adjuster's open edge closed, and get it aligned w/less understeer by a good alignment shop. If you want to really go nuts, gusset the steering mounts, fully weld the perimeter and the suspension mounting points, and maybe a 1-1 1/2" skid plate on the K-member.
