Thanks for the info.
Try Bosch #0221122392. It is a direct replacement for the original Bosch Coil, obtainable here in the US not sure about the UK?
Yes Britmog, this Bosch coil is available in the UK and I have one on the way now. Bosch list this for the 3.9 lit Range Rover so it should be correct. I can't see Morgan re-working the electrics when the Rover people have done all the work for them!
