You need a 2 groove pulley for the alt and ac, and a single groove ps driver pulley. The driver pulley bolts on top of the first crank pulley to give you 3 grooves. The 2 groove pulley is GM p/n 3744043 and the ps driver is GM p/n 3751232. If you are interested, I would take $40 for the pair plus $10 shipping. The ps pulley has 2 spots that look like pits, i'm not sure how these got here, the pulleys were an inch deep in grease. I don't believe the small pits will hurt anything since they were running like this.
Hope this will help you figure out what you need.
