I want to install my gun ring set up. Each kit seems to be different and done it’s own way, like what is used to install this system. Right now I’m just talking about the poles. Besides steel soldiers, where can I go to see the proper reinforcement brackets and bracing? Do I need reinforcement on the inside of the cab, Or just the outside with U-bolts? What keeps them from sliding down? Or does somebody have pictures of their install that I can go by? I got questions.
