3rd gen v6 power steering pump

Recently bought a 91 mighty max with a v6 and having a hard time finding a power steering pump with pulley. I bought one from a local part store that didn’t come with the pulley. So after taking the old one off the truck I realized the pulley is pressed on and the one listed by the part store has a key way and a nut. So it won’t work with the one that the parts store has listed. No one has a listing for the pulley separate. Even my local dealer says it’s discontinued. Does anyone know another pump from another year and or truck that would fit my truck? I’ve been playing the the years a what not at the part store but no luck. Thanks in advance.

pull one off anything with a 6G72, i would assume the SOHC and DOHC may be the same or similar. bracket mods may be required so be wary!
