trying to figure out the problem with my pulley alignment for my a/c. here's the problem. the air conditioning pulley does not line up with any other pulley, crank or idler. crank and idler line up. the a/c pulley sits too far forward about 1/2 inch. heres the skinny on the truck. its a 1993, with a engine(22re) from a 1990. the compressor stayed with the truck so it is for a 1993. my napa books show that a 90 and a 93 have the same compressor, but different clutch. unfortunatly i cant get any good pics and measurements out of the books to see if the pulley sits further back on the clutch than the one for the 93.

anyone stumble across this before? anyone know the difference between the two clutches?

thanks
