Dart 72 vs 73 susp dilemma

Hey guys. Thanks for the quick replies..

No offense but now I have more questions than I did when I started

Define. Spool mount, small bolt circle, k-h, u3?

Wtf does all that mean? J

So I guess I have to check the calipers for 2 piston vs 1 and that will tell me the year? (assuming 2 piston is 72 and one piston 73)

And the tie rod diameter bigger is better.

All the other stuff im on my own. Prob hodge podge is what I gather.

So, order all the **** for both years and return what doesn’t fit sounds like the new plan.
