The next step is to glue the sheeting to the deck, trim the edges, then position it. Before gluing on the sheeting, I will mount the tabs for the six 6x32 cap screws and mounts. Its easier to get to them before its sheeted. Finally once everything is positioned, one can glue on the back deck to get a clean interface with canopy deck.
BTW. I glued the 1/8 x 3/8 pieces to the underside of the rear deck pieces, added additional 1/16 pieces to fill the rest of the gap, only to find that I had to trim about 1/32 off the front and back for a flat mating surface (flat with the tops of the fuselage sides). A little sanding and it fit very well.
