Does anyone know or is there a site that lists the diameters of a 1973 water pump (original 340) with A/C? Getting soon to pull it apart.

The service manual states a 1:30:1 water pump to crank ratio with A/C. Wondering how this is achieved....

Because the water pump pulley on AC cars was/is smaller then the pulley on a non AC car.

On another note: AC water pumps have 6 vanes, non AC pumps have 8 vanes.
