I got part way there on our Amigo. Unfortunately I used belt tensioners that ran on the back side of the V belt like a serpentine so the belt life is very short (like 5K miles). I don't think this would be too hard to fix by reworking the idler/tensioner pullies. And the clutch chattered even without a belt on it. I suspect the chatter is due to engine vibration/harmonics. It was suggested that I use a rubber insulator like a piece of old tire to see if the chatter disappeared or at least diminished enough to make it usable. The P/S pump got moved to the driver's side to make room, and a custom hose made, along with bracketry to mount the whole mess and customising the compressor clutch assembly to get that extra 1/4" or so of clearance that you need.

Shameless plug: Hey, the whole motor is for sale including the brackets for the York setup if you want to come get it! :-)
