I finished installing the baggage sling today. Drilling all the holes in the aft cross tie and longerons was a bit awkward but I got the job done. Then the baggage sling was installed using the same screws that holed the inspection covers and tail fairings in place. (I had quite a few left over out of my fuselage hardware kit from spruce for some reason). Finally I went on and installed the seat belts. The cockpit is now finished as well :-).
