1:12 Mercury spacecraft instrument panel

I have discovered that the instrument panel in the new Atomic City model will have to be modified to model just about all missions.The kit panel represents a config. used on the last missions of the Mercury program,most of the spacecraft had the periscope display dead center near the bottom of the main panel.I need help for reference of the rear bulkhead,detail that is on either side of the couch i.e. survival kit,etc.
