Careful with that axe Eugene...
I can think (yeah, but not real well) of at least two different od shafts
for the non synchro trans. The early ones have a really small diameter at
the third gear end (farthest from the od unit), and that diameter has got a
spiral lubing groove cut into it. Be careful if you purchase one of the
"oldies, but goodies" as your likelihood of finding a matching fourth gear
are about as good as your chances of stumbling across that dual flanged
chrome plated escutcheon plinth...That shaft was set up to run on a bronze
bushing, unlike the later non synchro boxes which have a real bearing
between these shafts.
Other than that...yeah what he said...piece-o-cake.
