The aft and center fuselage skins are joined with 2 rows of riveted, but only the forward rivet holes are drilled in the aft skins. The aft row of holes has to be drilled by the builder by using the center skins are as a drill guide. The center skins have both rows of holes drilled. I accidentally add one too many rivets while installing the J-stiffeners. You can see the note I made to myself to remove the extra hole in the image below.
I match drilled the F-750 Aft Baggage Side Cover to the fuselage.
