I just installed an Orion behind my SM465 using my Promac plate adapter in my 73 fj40. My question is: do I need a spacer on the transmission output shaft? Will the gear walk back toward the transmission? There wasn’t one on there when I pulled the 3 speed case. My concern with adding one would be that it would make contact with the transmission output bearing. It is driving fine now. AA manual mentioned a spacer for the 4 speed oem transmission, but not the earlier transmissions.
I found a thread that talked about the adapter using the spud shaft, but mine uses a tapped replacement output shaft on the SM465. Sorry I don’t have a better picture
