The Shelby Mustang is a high performance variant of the Ford Mustang, built by Ford from 1968 through 1970.
Carroll Shelby terminated his agreement with Ford in the summer of 1969. The GT500 for the 1969–70 model years received extensive facelifts, the body alone increasing in length by 4 inches. Ford was heavily involved with design and style decisions, with Shelby having very little input. The GT350 was now equipped with a 351 cubic-inch V8. Production of Shelby Mustangs ceased with the 1970 model year. The 1970 models were in fact left over 1969 models.
