Take a copy of the logo to your local graphics shop and they should make you one up for around forty bucks or so each. Plus you can have it any color you want. Eventually that's what I'm going to do.
I have a Formula hat, floating key fobs, and I had a custom "Formula Outlaw" front license plate with the "Thunderbird' logo off to one side, white lettering on black background. My boat costs enough, I am not going to spend money on overpriced items. Guess I'm too cheap.
