I have two pairs of rear upper control arms sitting on a shelf in my garage. One pair is stamped 4997, and the other is stamped 2995. Are these date codes? Any difference between gen 1 and gen 2 rear UCAs?
The pair stamped 4997 weighs about 5 ounces less than the pair stamped 2995 and I'm just curious as to why. Different durometer bushings? I can't see any visual differences in the actual arms beyond the stampings, though.
