The gauges on all the models covered here can be replaced in the same basic manner. First, remove the instrument cluster and the front lens. Then, remove the gauge's attaching screws on either the front or the back of the cluster.
When replacing a speedometer or odometer assembly, the law requires the odometer reading of the replacement unit to be set to register the same mileage as the prior odometer. If the mileage cannot be set, the law requires that the replacement be set at zero and a proper label be installed on the drivers door frame to show the previous odometer reading and date of replacement.
