My original one even had some fitment issues from 3800 its all part of dealing with fiberglass parts
I should have been more specific on the elitespoilers. It does not sit flush on the center of the spoiler when installed on the trunk. I had a gen 1 as well and the only fitment issues was with some of the holes not lining up.
