Here we go. I found this image of the new two legged bridge made out of 6061 T6 aluminum flat stock while being test fitted.
Using the original tripart bridge to find center, mounting hole locations and depth for the two leg was easily done by simply mating them both at center with a few clamps and then scribing for drilling and trimming.
When I find the other images, y'all will see where this madness has a method.
