1966 Shelby Mustang GT350
The Shelby Mustang is a high performance variant of the Ford Mustang which was built by Shelby American from 1965 to 1968. For 1966, the GT350 lost its Mustang tag and was marketed simply as the Shelby GT350. The new model year also saw the introduction of non-white colors, including blue, red, green, and black. Other changes included special rear quarter-panel windows replacing the factory extractor vents, functional brake scoops on each side, and optional SelectShift 3-speed automatic, as well as an optional Paxton supercharger.
