First, Thanks for your service.
Someone may be able to take some pictures for you, I can't. Mine is a big block and wouldn't help that much. But, these things are still pretty common junk-yard finds. That would be a good source for everything you need. GM Performance Parts also has a serpentine kit that would give you every peice you need. New. Water pump, pwr steering, ac, alt, pulleys and brackets, not cheap though. I am considering the kit for my truck since I can't find the time to both scrounge and tinker.
