This shows the end of the panel. There is a piece of aluminum angle at the top on the inside. The Red arrow shows where there will be some screws holding the plywood to the aluminum.
The Blue arrow shows that the screws will go vertical through the aluminum into the bottom of the floor framing. This will allow me to remove these panels at a future date if I so desire.
There will also be additional bracing on the inside to keep this straight as well as adding a bracket to the bottom of the floor to keep the bottom of the plywood from flopping in the wind.
The original siding also had some braces at the bottom to help them remain in place and be sturdy.
