Riveted lower cross tie #1 & upper cross tie box to aft fuselage side skin verticals. Assembled drilled, updrilled, disassembled, deburred, cleaned, reassembled, riveted, and bolted upper splice plate on both sides of aft fuselage. Only thing left for SNX-F21 page is to attach the forward & aft push rod support assemblies which I chose to do at a later stage.
