After the fish ate the volunteers shown above, I was lucky enough to get 2 new ones (Terry and Anthony). They continued installing base plates,hangers and mounting 4x4's in place for the new lights.
One of the problems I had with the mounting steel hanging plates was drilling the existing steel. Here is a typical window. They are steel with a painted pressboard insert.
The wood is all PT exterior 3/4" plywood painted with a water resistant paint on the top portions and a waterproof paint (POR 15) on the lower areas which will get wet.
