Having done all I could to remove any distortion of the turtle deck, and having test fitted the two cabin windows, I now re-installed the turtle deck bulkhead laminated arches. These rivet to each other and to the FRP turtle deck and are bolted top and bottom to the aluminum main bulkhead. Plastic tie wraps are attached with some of the rivets on the backside of the arches to fix the fuel hoses, the wiring bundles, and, on the co-pilot side, the fuel cut-off valve aluminum bracket.
