Quote from StikboWhat is baffling is the GT fender badges. The seller painted over the original paint and swears that the running horse emblems were there with no MUSTANG letters. This guy was as straight as an arrow and I do believe him. So either the previous owner took the GT badges off and put the ponies on or it left the factory that way. That is of course if the consensus is that it also left the factory as a GT.
Nice looking car! Have you checked the front fenders for date codes? Maybe they were swapped out by the original owner?
