I have been playing with my cage. Decided to go to 5 point harness, cut out seat belts. Cut out nets. Welded cage together, welded in harness bar, .050 chromoly. Welded in top supports, arched chromoly. Welded in light bar support/surround. Welded in dzus tabs for the aluminum roof. I made the roof by molding it with a aluminum auto body hammer. Forearms are feeling it.
