"GM restoration" means absolutely nothing other than GM allowed use of its name and gets a percentage of the profit.

I don't know what to tell you if you are trying to find something that looks factory. I had a set of repop ones and gave them away for the same reason you don't like your set. For what it is worth, it will only throw things out of whack (highly technical term) if the upper ones are a different thickness. The lowers won't affect how the car sits.

I ended up using poly just because the quality control was better and all the pieces fit well.
