Raw pump Q

Greetings to everyone. I am quite a distance from my 1980 38’ Ericsson with Universal 5432 engine. I hope I can “blindly” order the correct Oberdorfer raw water pump impeller. If you happen to know a source or part number to order, will you enlighten me please ?
I realize it is a bit foolhardy to order parts without the pump at hand, but I am a hardy at heart.
I thank everyone for this wonderful forum.
