I replaced my km/h speedo with a mph speedo in the ex-mod 90. I guess they used km because their military charts are in km. (clicks?)

It will be nice knowing how fast I'm going without doing math. I also found a burnt out bulb, so now maybe I can see how fast I'm going at night too!

 

Did you get the right speedo rating for the tires, or you are going to have to do the math or use the GPS........

 

All the speedos are the same in defenders or most other land rovers. There are gears at transfer case that can change though.
