Spend a few bucks and join Air Corps Library and have access to the production drawings. The drawing you want, for the center panel is 10409. It's in the untitled section. Simply put 10409 in the search box and it will pull it up. Just to warn you, there are 4 instrument panels, 2 side consoles and both cockpit sidewalls used for instruments, radios, weapons, engine and wing fold controls. Busy cockpit..... That's from the F4U-5 series IPB....
