RV2 to Sanden conversion?

I looked at Classic's website. Appears they have a Sanden compressor kit for SB, BB, & RB, but price is "ask us". You don't need to currently have any compressor since they provide a bracket that mounts to the water pump.

For those with a York or Tecumseh compressor, which were a common in after-market AC, on ebay you can find a Sanden bracket that bolts to your York bracket. I have those on my SB and BB, but think too clumsy and heavy, so will try more custom.
