Left skin-removed part of blue vinyl on inside of skin. Clecoed 707 nose rib to top part of skin and riveted all except forward most hole. Clecoed the 708 and 706 ribs to skin and clecoed the 708 to the 707 rib. This pulled skin tight against forward hole of 707. Shot forward most rivet--very difficult to buck! Right skin-removed part of the vinyl on inside. Clecoed the 707 to top and bottom of the skin, as well as to the 708 rib. I think it was much easier to cleco entire rib structure to skin and rivet 707, than to do the top side of the skin/707 rib by itself. All looks good!
