1971 SBC short water pump height

[grancuda]

I keep getting water pumps from oreileys that put the water pump pulley about 3/8 too far out and I have shimmed the crank out and spaced out the alt bracket but want to correct it. Anyone have advice on making this right and where to get a water pump the right height? I don't want any shims on the crank, I just want it to be right, it was lined up with the old water pump and I just gave them my pump for a core and didn't think about measuring the height.
