2007 GXP, the third brake light(spoiler) is cracked and falling off. Is it the same part across all '04 and newer or is the GXP special? I'd rather not get a whole spoiler which is what the only local yard with GXP was willing to do. Does anyone know a GM part number if I have to try getting one from a dealer? I really don't want to plastic weld it unless I have to.

Thanks guys
