Hi Jeff the PT pulley is very simple and I'm pretty sure that they could be used on the F/C's as well. This means you don't need the taper pulley they fitted to the F/C's, just leave the boss on and bolt the pulley up using the standard washer and nut. Might have to adjust the motor up a bit to compensate What diameter is the aircon pulley? If I am going to have to fit F/C's to the later bases then I will need to get a number of adapter plates laser cut because it is too time consuming making each plate by hand. Now I am really on the hunt for as many F/C's as I can find
I wonder if these pulleys are still available they shouldn't be too expensive, they are only a pressed metal one, like an automotive waterpump pulley
