What is the requirement on two hooks or rings for race use? I have some extruded 7075 T angle about 3/16 inch I could slot the rear bumper and bolt it to the inside sticking out about 5 In. also how large Dia. hole for the hook is needed. the front end is also something I need to figure out with the slant nose bumper skin hanging about 12 In. past the bumper frame mount any tow hoop would have alot of leverage coming out of it. For the front can I weld a hoop onto the right side of the cage facing forward? I have no windshield so that would not be an issue for this type. Ideas or photos of what you have would help. Thanks

the rulebnook for where you plan to race will have very explicit instructions on what is required.
