Initial Suspension Settings for my Dart Before Alignment

There is absolutely a right and a left.

And yours are backwards.

Positive caster is what you need, and that means the top of the spindle should be leaned back toward the rear of the car. The tubular UCA’s have additional positive caster built in. When they’re installed correctly the upper ball joint should also be angled so the spindle would be layed back. Those UCA’s need to be swapped side to side.

I appreciate the follow up. Why would PST claim that they are interchangeable if there is a right and a left. It seems to me from measuring that the geometry of these arms is symmetrical (like a normal V shape) despite the optics. Can you tell just from looking at those pictures I am wrong? Not questioning your feedback at all. I just want to make sure before I bust all this stuff back apart. I assume I can support the lower control arm and assembly and just bust the upper ball joint loose and pull the UCAs out, if that is what I need to do. Or do I need to pull everything back apart? Again, I appreciate all the feedback.
