I will add this from my own experience. I have a 67 Barracuda with the variable speed motor. The switch has a couple clicks then a rheostat action to it. It had a later 3 speed motor wired in with the original variable speed switch and didn't work right. I obtained an original 67 (only? Can't remember) variable speed motor and it works correctly with the switch. Basically seems you need to ensure your switch/wiring matches the motor your using.
