Hmm, the weird thing is that the AC and PS line up with a groove on the crank pulley. Am I not sure of the PS pump and pulley but the AC can't be mounted any other way. I have a few different WP pulleys and every one of them is no where near lining up with the crank. Unless the crank pulley is wrong????

The engine that came out of the Jimmy was a 250 with the ALT as the only accessory so I am adding all of these items blindly I guess.
