I worked on bending the side canopy bows with very limited success. I placed 2X4's on the outside of the bow and laid a short block on the inside of the bow. A clamp was placed at the center and I then cranked the clamp tighter. I turned the block once so that the shorter side was against the bow and then tightened the clamp. This resulted in the bow getting a small kink in it.
