Sent my 300mm lens from my Fuji GX617 to be cleaned and was told it has seperation in the front lens group, the doublet element. I'm far from a lens expert, but I wanted to take a close look myself just to better understand. I took off the front retaining ring and used a lens sucker to take out the doublet element. But I turned the lens over and the rest of the elements including a spacing ring or whatever it's called all came out. Now I don't know which way the inner elements go back together and no matter what I try I can't get the lens to focus on the ground glass. It would be nice if there was an assemble drawing, but I can't find anything. Do any lens experts know how this lens goes back together? Long shot I know.

Yes, that helps. At least I can tell which direction the elements should go in. I think I'm close now but it's too dark out to try and focus. There was another ring inside the barrel that I thought was part of the barrel assembly. That's why I couldn't get it assembled. I should have it tomorrow.
