Dakota Dash are the people probably best suited to do the digital; as for all of the graphics for the tach and speedo, that would have to be custom built, or is that out of a Firebird? IIRC a Firebird dash that had similar graphics.
If that is what it's from, you'd be ahead if you could find a used one in good shape and adapt it to fit.
That's out of an 80s Stringray Corvette. The cool thing is, you can actually buy a used one online. But it's fairly bulky I think, and the overall housing is a rectangular shape.
Unless the price would be just totally astronomical, I actually wouldn't mind trying to design something unique that would fit perfectly within the dash space. Of course, I'm looking for a retro, Knight Rider-type, 80s aesthetic, but it doesn't have to be some huge bulky thing. Hell, if they could make it work within the two 3 3/8" spaces, I'd be totally down for that (and I could just keep the OEM mileage meter).
My only issues are who's gonna switch it out for me (and make sure it works properly) and will the gauges (especially the gas gauge) still register the correct level?
