Thanks Kevin, I forgot about the old car manual website, lots of good information there.
I have rebuilt one transmission in my life (also a 3 speed) and I recall using some kind of grease to hold the needle bearings in place before assembly. If I pull the rest of the transmission out and stand it on its nose, I think I can place all the bearings in and then carefully slide the main shaft back in. Not sure if that would be easier than taking the side cover and maybe the nose too to get at those bearings. I’ll figure it out. Hopefully!
