This is a correct reproduction C6 arm for a 1966 - 1969 FoMoCo pony car and midsize with a floor shift C-6 transmission. This also works on the 1970 as long as the lockout rod is removed. Midsize would be Fairlane Cyclone and the individual models associated with them like Ranchero, etc.
Replaces Ford Part #: C6OZ-7A256-B
