aftermarket instrument cluster

There were a couple companies that made them in the past but they went extinct in the near past. You can try and find one second hand as they pop up from time to time. Auto meter, year one, and Dakota make some replacement clusters for the later year A body's like dusters IIRC. Your best bet would be to mod one of those to work in your dash frame or if you search on here on some people make their own cluster.
