From VA:
https://www.summitracing.com/parts/vta-941170
"The Vintage Air 941170 air conditioning system includes a new compressor. When you place the order, you will be asked to specify whether you need a v-belt or serpentine compressor pulley."
So you can use the compressor with a V or Serp belt.
We have a vendor onboard that has the best prices I've seen - https://67-72chevytrucks.com/vboard/...d.php?t=642573

I'll second what Rocknrod said, MCB Matt had a great price and advise for what was needed. They'll send you exactly what you need.
