Mike, the 3rd leg is attached to the frame with a bracket. The manual tells you to mount the bracket to the frame with 3 self tapping screws. The 3rd leg is then attached to the bracket with 1 self tapper. Since the roll bar is sold as cosmetic only that was the way they did it. Many of the builders will weld the bracket to the frame and then drill through the bracket and 3rd leg and bolt it to the bracket. The manual has good pictures of the installation on pages 6-26, 6-27, and 6-28.
