Unacceptable: tubular upper control arms with no bump stop pads.

If it was that big of a deal, you should have returned the parts and bought the more expensive QA1’s with the bump stop plate included.
This is not a big deal to me. I didn't start this thread. I would not have started a thread on this topic, instead I would (will) call PST and let the chips fall where they may and nobody on this site would be the wiser. But since Greg mentioned my car, I felt compelled to at least acknowledge who the owner was.
I have spent thousands of dollars with PST on my Coronet and Dart and have had very good experiences; obviously otherwise I wouldn't keep going back. But I am disappointed in these UCAs, and I will never be convinced that because I had a great experience with the Coronet that I should not have applied that to the Dart. I understand hot rodding, and dealing with the aftermarket and I don't need my hand held. It is what it is and the bump stop issue has already been remedied.
Not being able to dial in any sort of reasonable camber and caster in the RH UCA is the overarching issue now. All the measurements taken point to something off with the UCA and tomorrow I'll see how PST responds.
