Transmission problems and possible solutions for a 22nd series Custom Eight

I reported my transmission issues couple of years ago. My transmission's 2nd gear on the main shaft has half tooth missing and the cluster gear is likely damaged as well. I did some inquiries to find a similar similar working transmission, but eventually I didn't manage to purchase anything.

I have been since looking for parts to revive the old transmission. The transmission has an R9 overdrive, so I would need a I reported my transmission issues couple of years ago.

I have been since looking for parts to revive the old transmission. The transmission has an R9 overdrive, so I would need a 354956 main shaft assembly, but I haven't been able to find one as a spare part. Max Merritt seems to offer one, but it's annoyingly expensive and my old one wouldn't probably give me the core refund due the broken gear.

But I'm pretty sure that the 2nd gear itself would be the same exact part with a main shaft that would be paired with a similar cluster gear and a synchronizer gear. The documentation says that the 2nd gear cannot be removed, but some shops seem to be refurbishing these. From factory they are pressed in to get some desired preload. So it probably has two (weirdly size?) ball bearings and some kind of locking crush washer that keeps the outer one in place.

So does anyone have any pictures or info how the gear and the ball bearing are assembled in the factory? My transmission is still in the car, as I cannot yet remove it.

I'm pretty sure that I could reattach the bearings with some method, if I just could remove them intact. The donor main shaft doesn't need to stay intact, if there is no other way to remove the gear and the bearings.

My other question is about the clutch splines. Does anyone know what is the Custom Eight's clutch spline? It should be larger than the splines used by other 22nd series models (1-1/8" 10 spline according to some source).
