Measure up 4" from the floor @ seat slider, and 3" from rear header panels at the base. This is where I mounted the belts from TeamTech. Both the lap belt and the submarine belts are attached at this point. Use an awl to find the hole then cut a small cross with a razor knife to allow access to the pretapped bolt hole. I have pictures to post but can't figure out how to attach them to this posting. If you need the picture send me an email and I will send the pictures or tell me how to post them. steve@tricelcorp.com
