The first two pictures below are of the drilling operation where the two fuselage F-826 and F-827 bottom skins overlap the bottom wing skins. These are drilled and later dimpled and nut plates installed to take #8 screws. The hole locations were previously marked by measuring 3" from the second innermost rib rivet line. This seemed a bit imprecise but it worked.

The picture below right is of the overlapped skins as seen from the floor under the fuselage.
