Well, first you can buy screw in chrysler ball joints with differant pin sizes, so no need to ream out any holes. Second, If your stock arms are in good shape, bushings ect, and your tires are wearing on the inside, then your alingment is INCORRECT no matter how many places have done it. In some cases you may need offset upper controll arm bushings, that will help you get more positive caster. Trust me my street cars all have factory arms, NONE of them have tire wear problems. The only reason we use tube uppers on the circle track car is because they are cheaper than factory arms, a hard shot to the wheel bends a-arms, and we can just call up and order them. We do use the chevy style mounting plate, again dirt cheap.
