Power steering pump pulley dimensions ford 1959 with select aire

Can someone help with the diameter and offset of the power steering pump pulley (the one on the pump itself) for a 1959 with A/C?

I know it is offset / dished out to catch the crank pulley third groove and different part number that the flat ones for cars without ac.
The problem is that there are other offset pulleys of varying diameter out there so i’m not sure which one is appropriate. (223 pulley is dished on 57, 60-63 tbirds with ac are dished but with different part number and possible different dimensions? Etc.
