those blitz din panels are/were very nice they way they would hold the smaller rectangular shaped items like turbo timer, boost controller etc.
i've seen a couple for sale on mr2oc off & on but they usually get snapped up quick.
you could prolly fab one up from thin sheet metal like the suby guy did on his.
i don't care for what that suby guy did with all the switches, not really my thing but the install was cleanly done.
i can't find it anymore but i saw a pic of a triple gauge pod this suby guy mounted on his dash - he molded it into the dash & it looked really nice. it was just above the clock/hvac vents area.
i like the idea of the switch where the lighter goes - good to keep in mind for something like a h/e sprayer bar switch.
