Billet pro shop custom makes coil covers. I spoke with them last week and said they would be making custom orders in a few weeks. If you cant find a source for style in your picture they will be able to make it for you if you email them the picture.
Yeah I talked with BPS and they are excellent guys to deal with. Unfortunately they cannot do the GT500 because of trademark laws with Shelby. I guess the back story was they did some with some logos but couldn't get a deal done with Shelby so they will do any custom wording just nothing with his name or cars.
