RV2 AC compressor Rebuild help

It’s a /6 so I think it’s a V2 compressor and it has the single groove pulley but I need the double groove to match up to my crankshaft pulley. I might just wait for an RV2 with the right pulley snd mounting brackets to pop up.

If it's a 1976 and has a V-configuration compressor, then it should be an RV2. The V2 was replaced by the RV2 in the early 60's, IIRC.
