First step to restoring my 1974 Duster; Front End rebuild (coilovers needed?)

Uhhh.....

I just saved you almost $1260.
You don't need all of those things.
You don't need the lower control arm kit unless yours are damaged or rusted.
Adjustable strut rods???? No. Try urethane strut rod bushings.
Pitman arm? Those rarely go bad.

Those upper control arms have Heim joints...They are terrible for the street. Noisy and harsh riding.

I strongly disagree on not using adjustable strut rods if he's going with poly LCA bushings. I've tried the latter without the former and it didn't work well (dynamic alignment issues). @72bluNblu can give more details on this. Basically comes down to the dimensions for factory strut rods being sh** and having less-compliant bushings in the lower arms makes it worse. Either do poly LCA bushings and adjustable strut rods together or go with rubber LCA bushings and keep the stock strut rods.

Otherwise I agree, tubular UCAs are nice but those ones are overpriced for what you get and Heim joints on that specific component for a street car are a bad idea. Also check current Pitman arm to make sure it is indeed still good.
