I must be confused.  Don't you mean P/N 105625 (Moss 841-010) ?  Both
sources seem to show it as available ... TRF even has a listing for used
ones.

ISTR they are considerably different.  The 4-synchro version has two
separate sets of teeth for 1st and reverse (because 1st is now constant
mesh); as well as being longer overall.

I certainly wouldn't give up the OD; it's not that hard to transfer to a
'new' box as long as you find the right mainshaft.  If you stick with
3-synchro, you can use your old mainshaft.

Another option might be to find a used 3-synchro box and rob the needed gear
from it.  There's some chance it would be bad as well, but that's not a
common failure so IMO chances are pretty good it would be OK.  

Or if you like I could even take a dig through my junk box (not now though,
maybe in May), there should be several in there and likely at least one of
them is good.

Yet another option (though not one I recommend at all) is to find someone to
try to repair the gear.  Weld the tooth back up, machine it to shape, then
heat treat the whole thing.  Probably cheaper to just buy a rebuilt OD
gearbox from John Esposito or equivalent.
