Guages. when I was driving them in the 1980s was as per delivered in imperial/.....MPH measurements.(standard M series instruments)
It would not have changed in service until they were desposed of in the late 1980s to 1990.
I remember the stop lights had to be turned on before driving them on a public road.
The other interesting thing was to double pump the brake pedal if you wanted to stop with a trailer on or you would get trailer only brakes and a big lock up with little braking effect.
