Just completed a 1500 mile road trip, at some point my passenger side kidney grill disappeared- at this point I don't know whether it popped off hitting a pothole or if some unknown douche who has it out for me ripped it off - all I know is it looks ghetto & I need it replaced. Dealer quoted me $187, and won't offer up the part #, so I'm looking to see what I could get it for from Rock auto or gmparts....but I need the part #!
