I've had the same problem on an old bay window bus. I ended up snapping a
hacksaw blade in half. I arranged the two halves so that the teeth faced
the opposite directions and put a small screw through the holes in the end
so that the thing would open like a jackknife. With some heat and patience,
I could grab the shaft hard enough in the teeth that I got the nuts off.

Another strategy that I would try now in the same situation would be drill
through the body of the joint and into the ball, and insert some kind of
pin like a nail to lock the two together.

You could also hacksaw or sawzall the thing in two.
