I have it installed and am ready to put the belts back on and now have what could be a problem. The power steering pump has a pulley for a three rib belt and the slot on the old HB is three rib. the slot on the asp pulley is for a for rib belt. my Z is a 1996. do the other years have a four rib pulley on the on the PS pump and can i get by using a three rib belt for a couple of days until i get a 4 rib pulley for the PS.
