Removed the shoulder anchors from the aft top skin, then removed the skin from the fuse. Final reamed #41 the holes along the lower edge of the skin where it attaches to the fuse skins and longerons. Match drilled 1/8” the gussets to the longerons, then followed up by match reaming with #30. Used a soldering iron to remove strips of blue vinyl along the rivet lines of the aft top skin.
