GM Perf. Parts Serpentine setup

[k5kev]

Has anybody tried using this Big Block serpentine setup from GM Performance Parts in their 67-72 (GMPP #12498733)? I'm in the process of putting in a 502 crate motor in my 72 suburban (with dual A/C) and was thinking this may be easier than trying to scrounge up all the brackets, pulleys, etc. for a big block. Maybe even cheaper at the end of the day!

I'm kinda wondering if it'll be difficult to adapt the a/c compressor and the alternator. Probably have to use R134? I'm pretty sure I can get the power steering pump to work. Any advice would be appreciated. Thanks!
