Yes I  encountered exactly that problem when trying, at very short notice,
to rebuild 6a 100S gearbox after the owner had trashed his as a consequence
of his TERRIBLE driving skills. He did the same thing again before selling
the  "S".
I didn't have a BN2 gearbox input shaft (the 100S gearbox internals are the
same as BN2) but I had a couple of 100/6 type.
Discovered that it was only the pilot bush spigot shaft that was longer and
simply cut about 1/2" (as I recall) off with a cut off wheel and all was
good to go.
