Hello Kris,
I would reconsider replacing those letters, it is a bit fun since you are in the US to leave people guessing on what type of car it is, some knuckleheads think it is a new model, because you see so few of them. I took mine off as soon as I got the car, but I have always been a fan of the "shaved" look, just a thought, nice looking car..
Happy Motoring !!!
