I'm a Canadian and have a 1990 5.0. That is a "Canadian" cluster for sure as the outer speed measurements are in km/hr and the inner are mph. However, on my 1990 5.0 the max number on the cluster is 220km/hr and the max for the US measurement was 140 MPH. I could be wrong, but it looks like your cluster was swapped out of a 1987-89 5.0 Mustang.
On my 1990 5.0, I'm a very conservsative driver and I always keep the needle on 120km/h. On my speedo, 120 km/hr and right at the top of the speedo. On your speedo, my 120km/h would be were your's reads somewhere between 90-100km/hr.
From 1990-1993, the cluster should have been the same throughout those years. If this is a 1993 cluster, then FORD just made the 1993 slower???????????????????
Why was the cluster replaced? A lame attempt to hide the real mileage on the car? OR, is your 1993 really, a 1993???????????????? Maybe, the last owner changed out the dash with the VIN and exchanged it for a VIN from a real 1993??????????????????
Someone with a Canadian 1993 needs to chime in here.
