Here is a picture for you. Note that I used two bolts for the installation. A AN4 bolt that replaced the original and an additional AN3 bolt at 90 degrees.
I also riveted a 4.5" by 4.5", .063 stiffener to the inner rib that holds the plastic bushing which secures the inner part of the step. This rib showed signs of flexing when weight was added to the step. The step is a rather large lever when you get a large guy jumping on it and a great deal of that load is transfered to the inner rib.
The additional forward inspection hole provides access to one of the com antennae and wire runs.
