Well I should have an xr3i set of clocks tomorrow, so I'll be trying them. If they work, I reckon the hardest thing to do will be putting the needle for the rev counter back on in the right place!!! (hopefully)

On the Escort RST this is an easy fix, but for cars with after market counters etc.. it must be anoying
