Ted,
As far as I know... the gearboxs are the same. The TOB is pressed on a large
bronze carrier bushing. The bushing has a hole that lets it slide onto the
front cover tube. It also has two flanges that provide a track for the pins on
the fork to ride in.
The TOB is replaced by "pulling" the TOB off the bushing and pressing a new TOB
on with a press or other means. However... you can put a new TOB on the bush
by chilling the bush in the freezer and heating the TOB in the oven to about
200 degrees. The TOB will slip onto the bushing quite easily if you act
quickly.
Under no circumstances that I can imagine... would the TOB be in play without
the bushing.
