I have an old car that I put a head unit in, but there isn't quite enough room behind the dash. The unit sticks out about a half inch. I don't have a problem with that, except that it looks bad. Does anyone know if there might be a spacer available for such a situation? It thought about making something, but I can't think of anything that would work, except maybe I could cut a piece of 1/2" plywood to fit and paint it. I'd rather find some sort of 1/2" plastic I could use, but I can't imagine where I could get something like that. Has anyone run into this situation?
