Yes, only the tiller joint connecting to the crossbar is missing on each side. The tillers themselves are still spring loaded. Regarding your advice about the piece of wood, what do you mean about jamming it "under the arm"--between the arm and the top of the hull near the transom, or where? I'm at work now and can't look at it, but I'm having trouble visualizing what you mean.

Hey, at least I know what a bung is now!
