I have been thinking about solutions to these problems.
1. Remove arm and make longer one
2. Lengthen pole by adding a larger diameter piped sleeve over the pre-existing one. This would rotate on the original upright pole and would go down to the brace on the hardtop.
3. Remove winch and place it on the upright pole below the brace. That way it would not rotate and stay fixed.
What would you do? I would love to hear any ideas that you might have.
