Grumpy,
That picture is the opposite of what I found. The large dia with internal spline was at the rear not at the gearbox end. Plus there was a defined stop when felt the final drive u/joint fitting.
PS.
not relevant to post but I was 40 years in industrial gear and u/joint manufacture, starting as apprentice in 1954 finishing as factory manager.
