Bulldog, I doubt you car get another one (as no one sells them now).
You will need to probably get it repaired if you want to keep the gauges consistent.
Or gut the mechanics of a new one and place it in the CR gauge.
I have used this place near me (they specialize in repairing speedometers) but they may be able to help you with repairing your gauge.
