What Happened to Carroll Shelby's Mustang Program at Ford

The first GT350 had no back seat — a flat sheet of fiberglass with the spare tyre strapped on top. Dealers told customers not to buy it.
It wasn't taste. It was a rulebook.

What no one else is telling you: the rear seat didn't come out to save weight. Under SCCA rules a car with rear seating was a sedan. Ford wanted to beat Corvettes in B-Production, not win a sedan class — so every street car had to match. The defining feature of the most worshipped American performance car of the decade was a paperwork requirement. Once the championship was won, the reason for the harshness vanished, and Ford took the car back one bolt at a time until 1970 it was a trim package.

In this video: Ford's homologation problem, Shelby American in the LAX hangars, Chuck Cantwell, the 289 Hi-Po at 306 claimed horsepower, side-exit exhaust, the Detroit Locker, battery in the trunk, three straight B-Production titles, the 1966 rear seat and automatic, the Hertz GT350H rentals, Klaus Arning and the "Shelby drop," the 1967 GT500 and fiberglass nose, the move to A.O. Smith in Ionia, the GT500KR, 789 leftover cars re-VIN'd as 1970s, and the Hagerty gap between a '65 and a '70.

If you've ever looked into the back of an early one, you've seen a rulebook committee's decision.
