The 1965, 1966 and 1967 Shelby’s were a series of Ford Mustangs, which were specially modified by Carroll Shelby's company and sold under the name Shelby G.T.
The new 1967 Mustang was followed with a new Shelby. It featured a 1967 Mercury Cougar tail light panel minus the chrome trim, a flip-up spoiler, and two sets of air scoops on each side. This was also the first American car to feature a factory roll bar.
This year saw the introduction of the GT500 alongside the continued GT350. The new GT500 featured a 428-CID (7L) big-block V8. This is also one of the most famous Shelby Cobras. A convertible prototype of the GT500 was made in 1967, which was designated to be scrapped. Before Ford Motor Co. could destroy the prototype, it was stolen. The car was eventually recovered by Ford and sold as '68 with the marque Shelby Mustang.
