Screeching fan belt, noise in the morning, and after the car sits for a while.

I have a 1974 Plymouth duster with a 360 magnum swap from a 2001 Durango. My question is does anybody have any information on deleting the A/C and power steering and only using the serpentine belt to drive the water pump, alternator. I need to know the belt and or tensioner I need to solve my problem. I will include pictures of what my set up is, any help would be greatly appreciated.
