I can help you out. Mopar started using Sanden compressors on the 78-79 I think 4 cylinders FWD and those years Slant 6 Volare and Aspen, with a single groove clutch for the 17 series belt that mopar used on there single belt systems. You can find these on Ebay most times. The single groove Sanden clutch is part number 5210271 and the clutch coil is part number 5210276. Vintage Air sells a bracket kit for 69 and earlier small block-part number 161004. It says you need to move the alternator to the drivers side. But I saw a 68 Barracuda that had this kit and the alternator fit fine in the stock location. I have one but haven't yet installed it on my 67 Dart.
