There were a few dozen rivet holes at the rear of the QB fuse that were left open. When the rivets are left out it usually means there is additional work to be done before they are riveted. For the life of me i cannot figure out what else possible neads to be done here; so I went ahead and finished it off with rivets. The most logical thing is that the rivets double as fasteners for the rear fairing, but i checked that and the fasteners for the rear fairing are plate nuts, and at different spacing. Oh well, it's done now.
