I wanted to run this by you and the other master mechanics on this forum, before I reinstalled my engine in the frame and tried to run it and became greatly disappointed. Here is what I did, I took the clutch lifter plate out of my 83 GL1100 and removed the pin that was in the center of the bearing. Here is a photo of the pin sitting on a 75 GL1000 clutch assembly;

You can see that the GL1100 has a pin and the GL1000 has a cup in the center of the bearing. I replaced the pin with the cup and installed it in the 75 GL1000, as seen here;

I would also like to use the GL1100 cover assembly because of the easier clutch adjustment procedure. Here are the insides of the two covers (GL1100 on the left)

and it looks like both just apply pressure to the center of the bearing when the cable is pulled. So what do you think, the lifter plates look different, but don't they just hold the springs in place and provide a place for the bearing? Let me know what you think, I have a whole clutch that I bought on Ebay (in the first photo) but I think the GL1100 has a heavier bearing and I would rather use it. Maybe Frenchy will want to chime in on this too, seeing how he has swapped a lot of parts between the GL1000 and the GL1100. I want to try and get it all back together by this weekend, my club has a run on the 19th. Big Mahalos in advance my friend!
