To answer your question Mark, I should have glued the two seat supports (D11), to the floor, added cables, then glued seat assembly (A21 & A29), to those seat supports (D11). As it was, I had to just clip out the horizontal members of the seat supports (D11), to allow complete seat assembly to pass over them. As long as we're on the subject, I'd also recommend drilling the holes all the way through the bulkhead (A18), to allow the rear ends of rudder control cables some free play. When I squished the fuselage halves together, it buckled the interior assembly, bending the cables out of true, and it's too late now to fix it, (the openings weren't completely through the bulkhead on my example, and I was too thick headed to correct it when I had the chance).
