Serpentine setups on the 92 you are getting, is a reverse flow water pump, as i also mentioned, the fan will also spin in the reverse direction from the older engines, i have a serpentine on my '89 and i also have a '94 Chevy truck with the 4.3 in it with the same setup.
Unless you just want to go with the serpentine kit you can get from like jegs or Summit, they just use new pulleys and all factory components, everything will still spin in the same direction.
