Sounds like you already know more than others! Most think 3pt on them, when only that bar with lift, have to explain that to them first. I'm not sure of answer for you. Myself liked the under frame cylinder much better, about 80 or 81 it seems. The had kind with lift on outside right of frame longer than that, not sure when started. I was NOT aware of one with only ONE adjustable lift link, that is new to me. Always thought same links on any 3pt. Have picture of the combination? Adaptations were made for earlier tractors to make three points mount to non-equipped ones, bolted to frame. Lots of changes over years, at times think they just came out at random, not really year specific for many items.
