That's a very Nice looking Early '63 GT Hawk, (Non-recessed Parking Lights) but the Dealer or Owner that installed that incorrect location Radio Antenna on the Right Cowl ought to be Shot!
I included a Pic of a '64 Avanti Powered GT with the correct Left Front Fender and through the Lower Cowl into the "A" Pillar Factory/Dealer Correct Location.
I happen to prefer the optional Thunderbird style Rear deck Antenna, but if it is front Mounted, it would be good to be correct on an otherwise Original, excellent condition Hawks.
