I don't recall what seal I used when I rebuilt the gearbox on my 750. I think I just used an O-ring. https://www.accessnorton.com/NortonCommando/gearbox-teardown-with-plenty-of-pictures.5107/post-53593
The 850 is definitely leaking and it's got an O-ring. I picked up some SKF 9815 (actually not SKF but same size and should be equal quality) seals. Since I have the cover off this is a good time to address is. Although it should be an easy process I may still make a video tutorial.
Given the availability of these seals why would anyone machine the cover for a different sized seal? You can readily order them from Amazon or eBay all day long. I happened to buy them locally because I was hoping to button up the gearbox today.
I'm not going to bother with the shifter shaft. There's no evidence of gearbox oil even getting close to that area.
