I like Your setup. It's not 62 Enzo, but a nice contemporary rendition. Would probably do it that way myself. No broken, faded kirinkle finish? (My dad's vintage plane has that- real old). Just no glovebox, huh? I'm sure you could find a way to cut a slot or something in there to stick your 'gloves.' Both of those dashes is supposed to have room for the heater controls, just not the center vents, which is I like. I want to keep my center vents: I only use vent, heat, defog anyway. Maybe you could mount the ound, side vents in the middle. Radio optional, of course.
BTW, have you ever toyed with the idea of putting a hose on the vent near your feet to the side vents, or just point it at the seats?
thx.
