Father-Son 1974 Duster Project

Considering which suspension parts to use for the front end rehab. Had a local alignment guy tell me that the pitman and idler arms don’t wear out on these cars but who wants to do all that work only to find they need to be replaced after the fact? She goes down the road straight, no shimmy but man she groans and creeks makes all kinds of friggin noise on bumps. I know I’ll stay with stock control arms. Not sure on the bushings, but for sure will add a Hellwig sway bar and a set of good adjustable shocks.
