I am also thinking that the original seats where secured via the OEM track and they seem to stay put unless the frame bends. As a result, I am thinking about finding the buried OEM track and mounting the base plate to the track using grade 8 bolts engineered to fit the track. I will also include at least four large lag bolts to go through nearly 1.5 inches of marine grade plywood. I am also thinking that with the seat belt systems in place properly that if your body was involved in enough kinetic energy to rip the pedestal base out of the floor my guess would be my body would not survive. Thoughts?Grant
