I added in my attachment doublers and nut plates for the static wicks. The inside attachment points are on their own doubler and are completely stand alone. They can be back riveted easily. The outer pair of nutplates can only be partially be done now. The rear nutplate is standalone but the forward nutplate is inside the tip rib which is attached later. The proximity of the core of the nutplate prohibits using the back rivet set on one of the rivets, so I set it with a hammer and drift.
