Today I finished making a cover/attach plate for the Rear Cockpit USB charger unit. Then I trimmed out the rectangular hole needed in the bulkhead, drilled new attachment-screw holes, and test-fit the unit, I sanded and primed the plate, and now I have to decide what color to paint it. I'm thinking dark gray. The attachment screws are black allen-head cap screws to match the military theme of the cockpit.
