Old AC D Grader. I'm needing a water pump that'll fit this machine. Any help from y'all would be greatly appreciated. I'd like to give this thing another chance at life.

Distance from bolt face of the water pump to the radiator is ~8.5"
Distance from bolt face of the water pump to the belt groove is ~4.5"
Water pump is a three-bolt type
Stamp on engine is WD 235548GA
Tag on machine shows D-4898

It should have the very common G226 engine also used in one of AC's most popular farm tractors so a new water pump should be readily available.
