Slant 6 904 TorqueFlight question

You will see in the service manual that the kickdown linkage is seperate from the shift cable.Both of your 63/64 cars have a rod from the carb linkage to the kickdown lever at the transmission.For you that will be using the Clifford intake a aftermarket cable setup like from Lokar is the easiest way to go.Bouchillon is another vendor with a excellent cable kickdown setup.
