Looking for a counterclockwise rotation water pump for a olds 350. Doing a serpentine belt set up.

 

Oldsmobile made a ccw pump. The 4.3 diesel used it. It was the first serpentine belt set up by Oldsmobile. ACDelco has a part number 252 635. Not available at this time from ACDelco. There is an article by Hot Rod magazine about this. See if I can attach the link.
Still looking for the water pump. https://www.hotrod.com/articles/olds...ne-beltdrives/

 

Is this some kind of special water pump?
​​​​​​​Rock auto shows several different water pumps with counterclockwise rotation for 4.3 Diesel.

 

I ordered one from rock auto. When I got it it was clockwise rotation.
