On the 94 & 95 Mustang ,if you take the speedometer,tach apart, on the back of the guage cluster at the bottom, you have the plastic gear case that drives the Odometer & trip meter. These gears wear out and break. Directly under the electric drive gear is a black gear that turns the numbers. Now for the problem, my black gear is broken. I need the enclosed gear case which is attached with three screws. ( Don't try to remove the gear itself, it will most likely break ) Help will be appreciated.
