Early a kickdown set up ?

Redfish - I believe the 67 and up style is the type that bolts on the intake. So the type that bolts to the rear of the cylinder head is the older design. What would be another clue is the throttle cable hold down. If your 2 bbl intake had a rectangular boss on the intake a few inches behind the carb flange then it used the older style kickdown, if not then its the newer type. I also examined a fsm for a 67 polara, in it for the 318 motor the kickdown linkage is the later style as well, which should have been similar to the ones used on an A body of that year.

You have a pm btw.
