I bought one of these emblems from eBay to cover up a gouge in the paint where someone pulled off the original dealer tag on the back.
It's a very heavy piece of chromed metal, and the blue paint has not faded at all in almost a year. I would say this is better quality than any manufacturer would use, I would call it excellent. They have them in blue, black and red letters.
The font for the numbers looks about the same as the font on the door sills you are doing, but the L is a little different shape. But a pretty close match if you wanted to have something that looks like a close match for somewhere else on the car.
They also have an emblem that says SUPERCHARGED that I imagine would also be of the same great quality.
They also have other emblems like V6, or something else just for fun like 7.3L
