Engine Pulley Help!

[LR1970]

Hi, I have a 72 Roadrunner and I need to work out which engine pullies I need. The car has power steering and no AC. Does this combo have a duel water pump pulley? I ask because I have a 67 R/T and this car only has a single water pump pulley and the power steering runs straight from the crank pulley, is this correct? The Roadrunner has a larger power steering pulley than the R/T so I guess I need a duel water pump pulley. Been searching the net for pictures but without success. Any help will be very much appreciated. Thanks for your time.

Thanks

Thanks for the picture, does your crank pulley have 2 different sizes or the same?

I just went through this with a 493 I am putting in my 73 satellite. I have the same PS pump and pulley you have, and I have the wame water pump as your second pic.

one belt from alt to wp and crank. one belt straight from crank to ps..my crank pulley actually does have two different diameters..not sure if it is right, but looks like it will work fine.
