I don't know of an easy solution. Maybe you can get this GM Performance 10055890 - GM Performance A/C Compressor Eliminator Bracket and Pulleys - summitracing.com to bolt into the PS pump location. I've seen them cheaper but this is the only picture I could find. You will need a pulley of some kind down there so the belt won't rub together.
