You have an aftermarket spoiler. The one in the first post is a GM accessory. Are you going to put the purple stripes over your spoiler too?I have this one called "tuner". Is it the same one? It's not installed yet, just sittin' on the trunk for this pic. My trunk is virgin, but I can measure the posts on the wing if needed.
I think the vertical mounting pods are shaped a little different, but I paid like 285 (painted and shipped)
Does it line right up with the holes on the trunks of the 06+
