Most are dash top, and really not huge compared to the rest of the interior items. I'm planning to build one for one of my builds, not sure which one though. Maybe a Valentine V1, or a Belltronics...

Anyway, I would take thick sheet styrene (.040 is the largest I've got) and glue pieces together until you have the desired thickness. Sand it to the shape you want, then get it really smooth with finer sanding. Take a super sharp pencil (you can get a needle sharp point by using sandpaper) and draw in the buttons and screen. Take a new #11 balde and carefully scribe in the details, don't go too deep or it will "ridge" around the line. Then paint it! (or cast a mold, as I do with most of my scratchbuilt stuff, then paint).

This is what I plan to do. Good luck!
