There is a problem with the newer design UPPER Control Arms... with some rims, if the backspacing is a little deep (and for some cars having wide rims... a deep backspacing is necessary), the newly designed adjusting bolts may hit the inside of the top of the rim or tire upon turning near-to-full lock. This could be avoided IF the new adjusting bolts would be relocated further in towards the engine.
Thanks for info.
Along those same lines with wide rim with high backspacing, watch out of tire clearance at full lock if you are running the US Car Tool inner fender shock tower supports. I know of an A-body that has that problem and they had to notch the support.
