Thanks 8pack! Yes they are including the R4 to Sanden adapter brackets.I am running that set up with a Sanden compressor and stock AC system with a HD clutch Fan. I can't post any pictures as my car is not with me right now. @bodymanbill is taking good care of it for now.
I can't recall if there was an adapter for the Sanden compressor. I think maybe a spacer?
