I fitted the front gap cover. This required notching out for the door hinges. I used a dremel tool for that. This was tedious work. Gap cover attaches to the horizontal door frame tubes at the the front using #6 machine screws and rivnuts, two per side. The fit is not very good over the airfoil curve, not a good match. I could see no way of improving this fit. I will use some door moulding foam to seal at final assembly.
