Serpentine conversion with electric fan

[Willis86]

I have a 86 C-15 with a 350 swap. Looking at doing a serpentine converion with donor parts from the junk yard. Been reading for bout an hour and I just got myself confused. So here are few questions I have after reading.

1. From one post I read I liked the 96-04 set up but is that 5.7 only or can I use a 4.3 also?

2. Water pump. Doing the BBC radiator swap that I got off of this site with the Jeep Grand Cherokee electric fan also from this site. So can I just buy a new water pump from the donor vehicle I find or do I still need a reverse rotation.

3. Can I use the same power steering pump as the donor vechile?

4. Was going to go with Four Seasons 161-58950 air compressor. Will this compressor work with the conversion?

Thanks for the help in advanced.
