I was about to get some of these as I have a thingy connected to the speedo cable to correct the KPH to MPH and allow a more sensible top end (?)

This bought after the garage had replaced the clockface with a corrected MPH dial.

How easy / Hard and potentially damaging are these to fit ???? (Lockwood Dials

The hardest part is the fuel and temp gauge. I managed to break my fuel guage, not once, twice. The needles don't come off them. The speedo and rpm counters are dirt easy and all you need are two teaspoons for leverage.

Cheers, I will give em a go ...
