I'm fairly certain that the fit problems stemming from the misaligned flap handle mounting bushing have been solved. Ended up twisting the top of the console by shimming it counterclockwise (used a -10L washer under the front left corner where it mounted to the fuselage frame), opening the slot a bit on the right side, and rotating the flap detent a bit clockwise.
Then, trimmed to shape and fitted the side panels and started on the adjustable pedal assembly.
