I would guess that the hole on the bolt head side is large enough for the compression tube to slide out. If you drill out the rivets on the bracket you should be able to remove the bracket and bolt together. If this is not the case, I would vote for cutting the bolt head off and enlarging the hole to slide the tube out. Trying to hammer or press the bolt through will likely damage the mast before the bolt comes out.
I agree. That's why I suggested

I have a feeling it may come out.
