My column is collapsed. I pulled it back to the original position ( indicated by a black mark probably put on at the factory ). I pulled the inner shaft out far enough and could see a recessed grove in the shaft. Should I put it back in the original position and say repin it with some small aluminum shear stock? I would think that would be strong enough to hold everything in place, yet shear in the event of an accident. Please advise.

Thanks, Gary
