I just did this a few weeks ago using everything from an 89 Suburban. Get all the brackets and accessories. I don't remember exactly, but I think the compressor bolts on differently than with the V-belt setup. You may need to cut the bracket by the fuel pump (if you have a mechanical one), because the empty spot for the smog stuff (?) gets in the way. I ran a new fuel line behind the bracket. Also, the thermostat housing may need to be changed; it may not let the existing hose clear the belt. You also need the water pump, because it turns in the opposite direction (as well as the fan). Hoses for the A/C compressor may be helpful, because they are shorter, but not completely neccesary.
Hope this helps. My swap works great, definitely better than those V-belts that would never stop squealing no matter what. I can take pictures if you need them.
