Broken torsion bar? Hopefully you could talk the seller down to a very good price.
I'd figure you should check the hinges to make sure that there isn't / wasn't extra stress placed on them. Or more importantly where they mount to.
Check with the top flipped & check for play/cracks. Climb up inside & check the same.
If you buy it, skip getting a replacement bar & jump rite to the torsion bar delete. Less stress on older fiberglass & parts, no worries about a failure in the future ruining a trip.
