Sorry the landrover ones will only fit the v8. I had just ordered them up for my v8 so had them in my mind.
The Dizzy cap for a 2000 is quite common, The 25d4 dizzy was fitted to mini and a host of other cars in fact this was the source of my last cap and arm. A good motor factor should be able to source them.
The leads might take a bit of digging around for, what you would be better doing is take your old leads to the motor factor and he can compare the lengths.
You can buy them from the suppliers on the main site but give you local guys a try first you might be surprised. Also you will get them from LSUK but I find that their price can vary from very reasonable to expensive but still worth a call.
