Re: 67 ac.
It all comes down to 67-68 short water pump or 69 and newer Long water pump.
67-68 Alternator on Driver's side A/C compressor on Passenger Side.
69 and up alternator is on passenger side. A/C compressor is on Drivers side.
I'm guessing someone has switched your car to a Long Water pump, and has switched your alternator and A/C around.
Just think of your car, as a '69 in this area.
