buy most of the parts for a 73 Dart: hoses, bearings, bushings, ball joints (upper and lower), control arm bushings. refurbish: spindles, Upper arms, caliper mounts, splash shields. degrease - wire wheel and paint. Don't paint the actual spindles though. beware of the FJM spindle vs. A body spindle argument! lol always a fun one!
For calipers; I opt for 78s rather than 73s. They have a larger bore caliper piston for a little more "umph". good to have if going with no power set up.
