Okay, here is the solution I used.http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&viewitem=&item=330111429548
I found the brackets all over the place at the local junkyard. I got mine from a 90's blazer for $40 for the brackets, idlers pulley, other pulleys and tension pulley. (Bring a steering pulley puller).
Anyway, the setup installed quite easily and I have a very nice stock look to my 502. The setup also fits nicely with just enough clearance for the dual spal fans and the be cool radiator.
If anyone else if looking for an inexpensive serpentine setup for their BB, I do recommend this.
