Need Help! Pulley, Belt Alignment V8

[v8pwrd]

Hello Guys! I need some help figuring out what i need to do with the setup I have. My car 355 V8, with Power steering , alternator, and Non AC.I have the triple groove water pump pulley , and just a double groove crank pulley. My problem is I think that the power steering belt runs off the outside groove(groove closest to fan,radiator) on the crank, water pump. And thats the groove my crank pulley is missing. Is it a must to run it off the crank Pulley? Could i just run it off the water pump and find a short belt? Or does someone have the correct crank pulley for sale ? Any help is much appreciated and will be returned someday!!! Matthew
