As a follow up, I am not sure if my engine had been modified before, but the lower hole on the block was not tapped. I had to tap this to a 7/16- 14 course thread and cut an existing bolt, slot it and put that in because of clearance issues below the water pump. This has worked well so far and has only cost labor instead of the $125 custom steel pulley cost from ASP. They were 1 week out on steel ($100 bucks) and 3 weeks out on aluminum($100 bucks.) Not to mention the guy I spoke with was a little bit of a prick...
So, the 2002 S-10 set up worked, but I had to tap my older style heads to accept two bolts instead of one on the left side. I made a bracket to connect the top part of both brackets for more stability. (I am a little paranoid)

I also had to tap and plug off the lower hole in the engine block at the water pump on passenger side, but the cost of the entire set up from a junk yard ran a total of $225 with shipping. MUCH better than the GM 1k asking price! Not to mention the A/C compressor is much better on the 02 models. I can post pictures of the setup if anyone needs more info. I am still working on some wiring issues, but that should be doable as well.
Thanks again for the help! Time to rock out!
