Google it, something like "remove challenger grille surround". You'll find it posted on a different Challenger forum, one that I am not allowed to mention. It is do-able, some guys claim to be able to do it in 15 minutes. I plan on removing mine and replacing with a special painted version. I bought a used one on eBay for cheap, and will swap it out after I figure out exactly what I want to do.
I have an R/T Redline edition which comes red rims and a red stripe and a body color grill surround, but it also comes with black chrome wheels. My dilemma is that my car is black so my grill surround is also black and I can't choose between painting the surround red to match the other red accents or going with the black chrome surround to match the wheels.
Decisions, decisions. :dunno:
If all you want is your surround painted, that can be done with it still on the car.
