Ok, I've found a couple which may suit. The one on the left measures 41.7mm and the one on the right 41.6. Sorry the photos aren't perfect.
As you'll see, the thread on the right one is better (the left one has had the bottom most section trimmed for some reason, but the remaining thread is still ok. The right one is curved and a bit shorter and the left is straight.
They are both missing the circlip that holds the cone shaped rubber boot down (which keeps the joint in tension), but you could just use the one from your broken shifter.
I'm happy to sell both together for $70, that way you could have a spare that would get you out of trouble in the short term.
Cheers
Jamie
