Here's another pic of the bracket from the front. I intentionally retained about 1" vertical on the cross member for rigidity. The eye bolts do not extend into the tunnel. Therefore, I can easily monitor and re-torque as necessary the eye bolts. I can't conceive the cross member bending any more than the tunnel sheet metal w/ washers versions. I do have 2" diameter washers under the cross member for each eye bolt. My mechanical perspective is since the eye bolts are inside the perimeter of the 4 mounting bolts they all share the potential load to the point of overkill.
I didn't fix the submarine straps to floor pan eye bolts because I didn't want to mess with relocating the computer. And I read somewhere about the seat cross bar being a factory option now with the advantage of the angle and length of the strap not changing as the seat is moved forward/backward. I guess I need to get official approval or drill some holes....
