Fan belt questions

I have a 72 dart w/318 with power steering and a/c. I have removed the a/c. Could anyone give me an idea of how the belts should be installed now that the a/c components are gone. My crank pulley has 3 grooves, alternator has 2 grooves, fan belt pully has 1 groove an power steering pump has 1 groove.

There is nothing running off the inner most groove of the crank pulley (closest to the block).
The middle groove of the crank pulley lines up with the alternater inner groove.
The outside groove of crank pulley lines up with the fan pulley and the power steering pump.
I think that the power steering pump should run by itself off the crank pulley and the alternator and fan pulley should run off of a different groove of the crank pulley.
Is there a deeper fan belt pulley that the groove will sit closer to the engine block and line up with the alternator and middle groove of the crank pulley?.

The reason I need help is I am getting a squeal from the power steering belt that will not go away. The tension is correct and the belt is new. I went as far as installing a new power steering pump thinking it would solve the problem but it did not. In all the pictures I found the power steering pump is running off the crank pulley by itself so I think that by having the same belt run the fan pulley it is causing the problem.

Any help would be greatly appreciated.
