Race Harness Help

I need help with working out minimum steel plate thickness and design to attach shoulder harnesses to. I have a 6 point Sabelt to install into my RF40, but the standard attachment points are too high for the shoulder straps. The first photo shows location of bolt holes in roll cage (10mm) and yellow dots (love hearts actually - thanks to my young daughter) where buckles will be bolted.
Second photo shows buckles. Third shows diagram with measurements in mm. (not to scale). Has anyone have physics knowledge to work this out? I assume approx. minimum force to resist deformation at strap point would be around 400KG??? I weigh 80KG. Thanks.
