We installed the nutplates of the aft flange (only 1 part of the piece for 1 screen - display) these nutplate were dimpled but the main piece not, this was dimpled by Van's. Attached the WD-1204 and F-01202-C-R & L and rivet, we use LP3-4 and a cherry rivets CR3213-4-2, we placed 11 rivets (cherry rivts) but we need 12, so we measure the thickness of the sheets and based on the results we decided placed other rivet, CR3214-4-3. The other thing that we did was installed the nutplate on the web of the piece.
With these steps we finished the page and the panel base channel
