With reference to my earlier post about resetting the Odometer, I figured out how to fo it, and in fact, I tried it on an old gauge cluster I had from the previous owner, as I wasn't ready to take my car apart yet....

But here's the next question: Is the odometer/speedometer/circuit board assembly (pictured,) the same for a 80 MPH speedometer as it is for a 140 MPH speedometer, and is it just a different faceplate?

Thanks!
