In my honest opinion, I do not think there is an "exact" location because I think they put them on in a little bit different positions from the factory. But unlike a lot of other people's Foxes I see, they DO NOT go way up like 7 or 8 inches on the fender. They sit down near the beltline, maybe AN INCH above the mouldings, CENTERED, although it is okay if they sit back toward the door a little more. That is how they are on my original paint GT, that has them in the correct spots.
