Today I worked on the F741 tunnel cover. The side angles required some work to get them shaped according to the plans. I actually did thing a bit backwards. I should have drilled everything in assembly with the fuselage. Instead I drilled everything separately. I have a bit of problem fitting the assembled cover over the tunnel. I have to spread the angles out just a bit in order screw the cover down to the floor. It's doable but I'd rather have it perfect. Not worth ordering new parts for though.
