Sometimes on the production line, stuff just happens. With the fender Mustang emblem used in the grilles being “handed” (a different-facing one for each side), it was only a matter of time before the wrong one got used in the grille. This backward horse appeared in the grille of a car still in the possession of its original owner and he confirms that the car came that way from the Shelby dealer. A “wrong way” grille horse is also noticeable in one of those “guy and a girl and a car on the beach” GT350H promo shots, so there’s more proof that it didn’t happen just once.
