I wish SOMEBODY had already tried these!
A Nordskog main panel and an auxillary panel I have yet to design are Item #7c3.b on my "Interior Of The Gods List, As Appended."
Nordskog comes in three basic colors - a "cyanish," out-and-out green and amber - red is available for some things, but not True Blue, which I also favor. They DO make these for early C3's too, not just post-'77's, but you may have to go to their homepage.
Dakota Digital and Dolphin also offer complete lines, and others do specific gauges. I believe "CyberDyne" (who made my Air/Fuel gauges) are a division of Nordskog now.
I want the Nordskog for two reasons:
1) The huge circular design of their speedometer and tachometer, with multicolored range indicators, as well as the digits themselves, which I feel beats up badly on Dakota Digital's straight bar. (Even though I wish it was available in the pure blue of the DD's.)
2)Nordskog's huge rep with the StreetRod, Custom Rod and Land Speed freaks. Before Dedenbear, Nordskog was THE source for domestic Data Acquisition and other higher-end vehicle electronics (early '70's.) Now many companies offer good products (including these gauges.)
My big concern with all of them is I would like to know how subject to direct sunlight washout they are - how bright they are at 4:30PM when you're flying northeast like a low altitude interceptor across a burning Texas landscape in August with the sun pouring in over your left shoulder (where you sit in icy cold comfort in your 170 degree front seat, because you're insane and in a vette with terrible (or no) A/C...) :Silly
I have seen these panels in custom rods for years, but never recessed like in a vette. I am therefore stupid enough that once I get the OD, the Vintage A/C and some minor engine upgrades on the temporary baby block crate motor, I guess I'll find out...
Of course if you got yours now, since you are ready now Mister! you would do me a huge service! I'd be your best buddy even! I might even remember you when I write my will - wouldn't put you in it of course, but I might remember you when I wrote it! :love
