Default DIY Junkyard Serpentine system

Hi,
Im in the final stages of putting together a serpentine system on my pontiac 400. All worked out well but I did not hook up the ac compressor yet. The crude spacers in the pic are just a mock-up for measurements. I will install actual spacers and an aluminum block behind the power steering bracket once I know exact dimensions. I did a search on diy serpentine systems for pontiac but came up pretty dry.
I am looking for anyone who did one and included AC to get some ideas. I have a couple options.
1- leave the existing v belt pulley behind the new serpentine crank and run the stock compressor as it ran before or
2 -install a newer style compressor in front of the cyl head and find an existing bracket in the junkyard that I can modify to mount to the pontiac.

I sort of have #2 mocked up right now and would love to complete it that way. Its a larger diameter stubby style compressor. I think it came from a third gen firebird. The factory AC lines fit right onto it. Has anyone installed one of these on their pontiac?

Also, if anyone would like more info on what parts I used to do this let me know. It was actually less painful than I thought it would be.
