Eyeballing the engine picture, it appears you have the 1967 clutch on the compressor. It is thinner than the 1965 1966, so that is why it will "work" on a 2 groove pulley.
I have the correct parts for the PS set up, and AC set up if you want to call me sometime.
Maybe what I have is a dealer add AC unit. Bob, you sold me the 3 pulleys and bracket, I havent done anything with them yet.
I also need to figure out which WP I will need. The car is due cooling system maintenance and the heater core just gave up so I may as well tackle it all at once.
