1965 Dodge Dart 273 with A.C. Pulley Questions

I know I'm reviving an old post. I have a 4 sheave crank with a factory A/C car witha double sheave RV2 compressor. I see alot of differing opinions and I'm trying to decipher facts. 66 had 2 idlers. I cannot find a true 65 diagram and varying pictures of diagrams. Apparently 65 is a year where they experimented different designs. Does anyone have solid photos of 65 year design in functioning order with a double pulley compressor and whether or not they used idlers as well as relative photos to routing of the belts?
As I look at my pulleys, the power steering gets it's own, of course. But the alternator has a double sheave, and one is used with the fan/water pump pulley. How in the world do I route the outer sheaves to the a/c? And is one shared with the second sheave of the alternator? Or should I have a single alternator pulley with a tensioner for the 2 for the a/c?

So many questions, too many different designs, and not enough factory literature to provide a concrete answer.
