I recently installed the PST uppers on my 71' Barracuda and was really pleased with the quality of their work and the weight of the rod ends. They installed easily and fit perfectly, but will definitely require a tech who knows his stuff for an alignment. With the engine installed and the torsion bars where I want them (as far as I can tell as the car is in pieces) the frontend moves very very freely. I had QA1 uppers with rubber bushings on my 67 Coronet racecar and they were a step over OE. I feel the PSTs are a step above those.

I'll also be using the greaseable lower bushings but haven't installed yet.

You can see them up close in the videos (the disc brake install, at the end) on my YouTube playlist in my signature.
