Dart 72 vs 73 susp dilemma

Hey all,

FNG here. Thanks for having me, glad to be here.

Have an interesting scenario here and could use some help.

I have a 72 dodge dart swinger coupe - manual steering manual & front disc brakes..

Car was originally a slant 225 (per fender tag) and before I got it, someone converted to 318 from a 73 (I have checked the block to confirm)

When they did the swap, they did the k member and motor from the 73. (and maybe the brakes)

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

Now my car is getting older and could use a front end rebuild that I want to do myself then roll to the alignment shop

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? .

secondly, it is my assumption that most of the front end stuff except maybe shocks are different between the years.

I don’t know dodge so when doing a k member and or brake swap (I cant confirm that the discs were swapped), would you typically convert all the front end to match the K member?

Or… Would you retain the 72 stuff and just swap motor and/or brakes

Or.. worst case scenario, could my car be a hodge podge of mixed year parts?

Thoughts, suggestions, insight or direction appreciated?
