Fully adjustable upper A-arms for ‘67 Barracuda

You shouldn’t need the QA1 eccentric bolts unless your factory ones aren’t any good. And you should be able to achieve more than +3° of caster with the QA1 UCA’s too.
fair point. i figured QA would pull some BS like having specialized bolts to go with the arms because some aspect of them doesn't jive with stock hardware by jussssttttt enough.
