I'll bet you a dollar it is. You are correct that most GT Mustangs came with the FOG switch mounted farther up, in a drilled hole. The hole I show was a correct, D-shaped hole, provided for the FOG switch, especially in convertibles with the power top switch. Ford later moved the switch upward, on most, but not all, cars. However, nothing says you can't use the original, factory stamped hole, especially on a clone.David, that's NOT the factory mounting location for the fog lamp switch. It is actually mounted further up on the curved face of the dash. You have to drill the hole out for it.
