mechanics, I need your help! Serpentine conversion question

[YOLO]

My project is a 64 C10. My 350 sbc is from a 70 Camaro. I want to put a 99 Chevy Tahoe serpentine with A/C on my 70 block. I am told there may be a problem using the stock water pump from the 70 Camaro and maybe a fan direction issue. Does anyone know if I this conversion will "fit" and if so do I need a water pump from the 99 Tahoe? If there is a fan issue do I just get rid of the mechanical fan and use electric fans? Thank you.
