I'm replacing my water pump on a 235 engine. Truck is a 1951 Chevy. Having trouble determining if it is the short shaft model water pump. I believe it is, but the pictures of the new short shaft pumps seem to have a smaller pulley attached. Do I use my old pully or the new one that comes on a replacment pump?

Does anyone know if the short shaft pump in the Chevy duty magazine comes with a pully? If not, it mentions in shop manual that a press is needed to put the old one on.
Thanks! cool
