Serpentine question with vintage air

[jetfixr]

I was thinking of going with a serpentine kit to clean up the engine bay. The truck is a 70 c10. The PO put a different engine in it, I decoded the engine code stamped on the engine. It's nothing special, looks like it came from an 83 truck. Currently it has a long water pump, the PS pump is on the drivers side and the alternator is high on the passenger side. I understand I may have to switch to a counterclockwise water pump to work with a serpentine setup. I am not looking for anything special, doesn't have to be billet or flashy. What would be cool is something functional and inexpensive. I do not have AC now, but I am planning on going with a vintage air AC kit, and the compressor on that thing looks massive. I would like to find a kit that will work for what I have now, and accommodate the Vintage Air compressor in the future. Any ideas?
