I have a GT that I got in October. I want to put a firefighter union sticker on it. (They are similar to a get out jail free card, with state troopers! Professional courtesy. ) The stickers are the Maltese Cross and about 4 1/2" square. I don't want to apply it directly to the plastic on the rear fender and it has that ridge in the middle for the sliding mud flap. Anybody have an idea on getting something to bolt into the existing holes that would be flat for the sticker? Thanks for your input!
