Any elaboration on this? There are 2 different deck lids manufactured based on the type of spoiler?
Wacky. I'm seeing 3 different part numbers for the deck lid.
GM Part # 84568187: Standard deck lid
GM Part # 84568188: Blade spoiler deck lid
GM Part # 84568190: Stanchion spoiler deck lid
Color me surprised. Guess I'll need a new deck lid if I want to change the spoiler out, like the OP.
