What Color Are First Generation Barracuda Grilles Supposed to Be?

Well if the consensus here is body color...my as cast neutral grill is gonna get a shot of silver paint...and I may even address the blacked out "Low brows". Mine must have been a replacement grill @65 Cuda 340 mentioned as they were "Customer facing" going down the road, and made of an unforgiving cast aluminum or zinc or pot metal that would most likely break instead of yield to a stone or something. Question: how do you correct some minor waves in them there grill slats? Gentle persuasion with a wooden wedge or something?
