My roll cage is mostly done and now I need to think about upgrading the lap belts. I did not put "X" bracing in the main hoop because I have people getting into the back seat often and this is still my daily driver. Because of this and the style of seats I have, I cannot use a 4-point type seat belt. So my goal is to attach a 3-point to the cage. The seats are tied into the cage and the cage is tied to the frame. You can see it here: http://www.wheelingarizona.com/forums/viewtopic.php?t=6377 What are some of the ways you all are attaching your seat belts to a roll cage? Mainly I am talking about the shoulder mount. Should I weld a tab or drill a hole through the bar? I would rather not drill the hole for structural reasons. I have searched and all I have seen so far are 4-5 point harnesses and a fancy clamp that clamps to the bar (a fancy home brewed clamp.) What other ideas are out there? Pics would be appreciated.
