Alignment Issue QA1

[79T/Aman]

the offset cross shafts only affect camber, DSE uses mounting slugs to shift the arm for and aft to affect caster.

From what I can tell the guy at QA1 does not seem to know what he's talking about, according to QA1 the upper arms have 3-4* of built in positive caster, this means that your car when it had stock upper control arms had around 6-7* of NEGATIVE caster!!!!!!! stock caster setting is typically around -1.5 to +1.5, I don't know what it is exactly but you can see it is way off the opposite way their arms are supposed to change it.
A-body arms are very symmetrical and not out of the realm of possibilities that the sticker was put on the wrong leg.
