Its defenitly aftermarket. And Im going to go with it being a Wings West spoiler due to the fact that their fitment sucks (so I read on LS1Tech) The spoiler fits no doubt about it, lines up in to the wholes perfectly its just rought on one side. We'll see I tried going to the auto parts store looking for similar studs but I had no luck with finding anything close. Im going to try my friends massive collection of bolts, hardware store, then god forbid... dealer.
