Late W56 input shaft different?

Greetings all
I am currently rebuilding a late w56 (E?)transmission to go into a 4wd Chinook camper conversion I am building. Unfortunately the pilot bearing on my donor truck chewed up the input shaft and I need a replacement. All of the W56 input shaft replacements I have found are for the narrower input shaft bearing and early style synchro rings, even though they are listed as fitting up to the 1995 W56.
I have ordered and had to return a couple of input shafts and am a bit stumped. Does the late (post 1991) W56 with the wider input shaft bearing share an input shaft with the later (W57,8,9) transmissions? Any help here would be greatly appreciated. I'd love to get this transmission back together and get on with this project!

I think I figured it out.
I believe that the late W56 input shaft (post 1991) is the same as the W59. I have one Coming. I'll confirm for posterity when it arrives.

Yup confirmed. The late W56 uses the W59 input shaft.
