1967 formula S convertible production
The 1967 record still exist. You can get a copy of the IBM car for your car, but cannot get all of them. There were 457 1967 GTS' built with an unknown number of convertibles (assumed by some experts at less than 20). There were 1,784 383 Barracudas in 1967. Convertibles were 6.8% of total Barracuda production. Even at 5% there would have been around 90 383 convertibles.
