I just pulled a broken one out of my 292. Find a bolt that fits snug inside of the tube (5/16" if I remember correctly), set it inside the tube, length doesn't really matter, clamp the tube with the bolt inside of it to prevent it from collapsing with your vise grips and just give it a couple of rotational twists and it should pull right out. If the split is at the top, I would use a longer bolt (even threaded rod will work as you are not going to damage it) and then clamp on below the split.
Good Luck
