Thats brilliant thanks Jack.
All I have to do is find a mk1 set of clocks now.
Also the clocks I have in the car look more like the 1st set of poverty spec clocks pictured above. I'm going to have to have a look at the back of them and check the wiring as they may already have been chopped and changed for a mk2 plug - this car has had a lot of work and I wouldnt be suprised if its had rev counter clocks before.
