upper control arm

I called the an ebay site advertiser in July that had stamped upper arms, The guy told me they were made "offshore" and he didn't know if they were big (73 up) or small (72-64?) ball joints in them so I went with the tubular style uppers(they fit good but there were no provision to hold the ball joint grease boot against the inner arm and I needed to lengthen the upper bump stops to hold the arm from damaging the grease boot, If I had known about this issue I would have looked harder for a good used pair of arms.
