Mopar small block fan routing diagram

I have a 340 that I put in my 73 dart and I am not sure on the belt diagram for it. I do not have AC. I believe it would be two belts One for the alternator and one for the power steering pump. But I'm not sure of the diagram on either one or the belt sizes. I have gotten several belts from my local parts store but none seem to fit right. So any information would be helpful thank you
