Don't feel bad, I put my first one on the wrong side (and it was a 50/50 chance because I didn't know that was possible either). I caught it before fully assembling the truck, but you're not the first to get control arms backwards or the centerlink reversed.

Your average alignment shop could likely spot a backwards control arm on a Camry or Accord maybe but most of the guys in there will not have worked on a 67-72 truck very often, if ever!
