I'm inspired by the hinge design on this ash tray lid
I think I may be cutting up that black dash cover and making a single DIN opening with flush closing lid. Maybe use the old ash tray knob for it. And maybe make it wide enough so the wideband gauge can hide in there as well, it is not a gauge I'll look at too much while driving.
Further considerations for an overhead console: the way the factory headliner fits a console would either hang down too much or need to be recessed into a custom headliner
