Dart 72 vs 73 susp dilemma

Oh and wanted to mention also, the brakes are a slide type caliper if that helps..

I want to do everything at once, i.e. control arm bush, BJ’s, Idler/pit, tie rods etc, etc

My confusion lies within the swap. First off, I am under the assumption that you couldn’t get disc brakes until 73 so was that swapped in? .

If you have slider calipers, sounds like the whole K frame and suspension was swapped. If you have spool-type engine mounts and a 4.5" bolt circle, that would support that theory.

Disc brakes were available in '66. Up to 72, they were a fixed caliper with 4 pistons make by Kelsey-Hayes.
