Interchangeable A833 input shafts

Hi!
I´m about to start restoring my A833 transmission, something i have never done before so looking for some guidance here from the mopar community.
The trans I´m about to restore is from a 68 Dart, it will now take place in a 71 Duster:
Maincase: C-97622
Tailhouse: C-97477

The transmission I´m about to restore had a whining noise from 1st, second & 3rd gear.

When reading in Jamie Passons "How to rebuild A833 transmissions" I think that the problem is the bore in the input shaft? Which I guess means that it could need replacing.

But I have another transmission from a unknown car that looks ok. Probably a B-body 66-68.
Maincase: C-97622
Tailhouse: C-96707

My question is: Would the input shafts be interchangeable between these to transmissions?
