You should have a long pump. The long pump is longer from the block to the pulley and has bolt holes for mounting accessories.

If the car has a serpentine belt then it's reverse rotation, if it has V-belts then it's standard rotation. I don't know if there's a way to tell the difference externally without taking it apart to look at the impeller.
