140kph to MPH speedo

So my speedo stopped working last week, it is the 140kph (not the 200kph) style which has a trip meter. I ordered the cable for 5 quid hoping that solves the problem, but if it turns out to be the speedo itself I will just put an MPH speedo in it.

Do I have to change the cable to put the analog MPH speedo in? I have Cable PRC6023. This would be going into an LT95 with 1:1 transfer case ratio if that changes anything.

I would like 1 rover with a working speedo.

If it's a standard defender type speedo, then they're all the same, it's the drive gear in the transferbox that alters the actual "speed" shown.

Older series speedo's were calibrated in the speedo head itself for various tyre sizes.

so in answer to yer question, just swapping the KPH for a MPH is just a swap job.
