Front end rebuild on 1967 Dart

So while I had the center link out to install headers on my 1967 Dart, I decided it would be a good time to replace worn out front end components. I am a rookie at all this, so I wanted to run this by some more experienced minds.

I’m looking at a Firm Feel '73-'76: H.P. kit; Urethane Bushings, 11/16" Seamless Tube Tie Rod Kit (with tubular upper control arms) Firmfeel Mopar Suspension and Steering
This is so I could pair it with a Doctor Diff disc brake conversion kit that uses 73-76 spindles. It is my understanding I would also need a 73-76 center link for this to work. Is this a sound plan? Am I missing anything? Any advice or experience shared would be much appreciated. Thank you.
