I think I might have found a picture of what you mean Matt G. There would be a plate that bolts onto the 3 pt and the gear box would just slide on and get pinned in the top where the top link would normally go? There are to little fins at the bottom of the handle bracket on the back of the gear box and my guess is they would just ride on that plate in the grooves on the back of it? And the bottom of the gear box mounting frame would be pull against the plate by the tension of the belt?
