I had the entire K frame out when I restored the car. I knew to look for cracks. Didn't see any. If it was some kind of damage from an accident, I don't think it would be both sides moving. And if it was me, why did the 2 alignment shops have the same issue? I have a 64 Sport Fury, and those adjusters haven't moved in 15 years. I will look at the lca bushings, and the washers with nubs.
