Parts stores list three belts for the 84, but only two are used at one time. One for the alternator, crank, and water pump. The other one was EITHER the crank, water pump, a/c, OR crank and a/c only. If both pulley grooves on the crank pulley are the same diameter, then you need the belt for a/c, water pump, and crank. If the outer pulley groove on the crank is smaller than the inner groove, then you need the belt for a/c and crank only. I think the early 84's used the a/c-crank only and the later ones added the water pump pulley.
The belts should not be offset. If they are you need to check and see if you have a bent or loose mounting bracket on the alternator or maybe the pulley on the waterpump has shifted on the shaft.
