I sincerely doubt that it is a 1979 because it has the narrow license plate opening - unless the rear clip was replaced for some reason. You will know for sure if you can get the seller to send you a photo of the engine compartment and the VIN plate. If the engine bay is made of squared-off panels, then it can be a 1979. However, if it is made of the original rounded Ford stamping, then it will be a pre-'78. Similarly, if the chassis number is lower than 9000, then it will be an earlier car.
