The second year for the Shelby Mustangs. The early 1966 Shelby Mustangs were left over 1965 cars with the suspension modifications. When the supply of those Mustangs ran out, the balance of the 1966 Shelby Mustangs did not receive the racing suspension. They did get some Shelby Mods but nothing like the 1965 cars got. This was the first year for the Hertz Shelby Mustangs.
