Cadillac STS Forum - 2005 through 2012 Discussion, Replacing 08 Lower Grill in Past Cadillac Vehicle Discussion; On a 2008 bumper will a 2008 lower grill platinum edition fit just as the black lower grill ?
I asked my dealer this exact question for my 2013 EXT. The parts guy printed up the parts diagram for both and they don't match up. Looks like a lot of parts are different. I'm currently looking for an aftermarket solution.
Right but I could look at the escalade and tell you the platinum and regular grilles aren't interchangeable. In the STS case, they're the same dimensions. I would be willing to bet it would fit. No guarantees though.
