This is a very "early take off" speedometer assembly. This is a dual speedometer with 110 MPH and 180 km/h. My guess is that someone bought a new MPH speedometer back in the late 70's and then put the factory original speedometer back in the box. This part is in excellent condition and will look great in your show car. This speedometer shows just under 27,000 miles. It is dated on the back with date code Sep 20, 77. This is an excellent part for your Canadian built car. Fits all 1978/79 T-bird, Cougar & LTD II. 

Please look at the pictures to verify it will fit your application.
