Upper control arm advice

Magnumforce double adjustable UCA’s are not something I’d run. Their reputation is pretty lousy.

SPC UCA’s are double adjustable and use a much better design than the Magnumforce double adjusters. @BergmanAutoCraft sells them. Not cheap but very easy to use and you can dial in pretty much any alignment numbers you want.
SPC does not have them for A Body.
Bergman does not have them for A Body before 1973
