Rocky JS,

1967 Plymouth Barracuda was 'introduced' to the Dealers on November 15, 1966.

On the 'new' 383, the Plymouth Production Line was dropping in the 383 Big-Block Engine from the
top on the A-Body cars.

The 1967 Barracuda 383 'Formula S' was only available with 3.23 Gears 'Sure-Grip' from the factory.

Dealers were told, 'not' to offer any Dealer Installed Gear Options.
