[Fot] early TR3 input shaft question

[rkramer3 at austin.rr.com]

I have an early TR2/3 non-synchro first gear overdrive tranny that I am rebuilding. The mainshaft was trashed so I bought one on eBay but it is different in an important way. The old one was similar to the ones that I'm used to seeing in a TR4, the input shaft rides on a caged set of rollers on the snout of the mainshaft. This early one, according to the Moss catalog, takes a $39.00 bushing on a much smaller diameter bearing surface. It is also longer which I think is an important difference requiring an early input shaft that I don't have. Does anyone know if the diameter of the early style TR2/3 bushing mates up to the inside of the later input shaft diameter with the bearing removed? I figure I can trim off a bit of the mainshaft and bushing and make it work if the bushing mates to the later input shaft.
