I recieved a new radio bracket from DMC houston as my X-mas gift from my wife. I have a question: WHen i looked at my original radio mount (the one I do not have to cut) it has a black plastic "covering" that faces out into the cabin. The new mount I got is all metal, and I assume it goes UNDER this black plastic. My question? Won't I still have to now cut the black plastic for my CD player din sized radio to mount? If so, what was the purpose of getting the mounting kit? Kevin Abato Vin #16680
