The reason the paint is off most of those plaques is that they are all chromed. This makes the surface to slick for paint to stick very well so it doesn't last long. If you are looking for anal OEM perfect paint match don't read any further. But by having several formula S cars, both 383 and 340, I have found that Rustoleum spray paint number 7250 black night metallic is amazingly close to the correct background color around the numbers, especially when it ages a little. For the other black color I use plain old semi gloss black. OEM perfect no, but I'll bet you don't find anyone that will question it, other than to ask the paint name so they can use it.
