Many thanks once again for those of you who have offered advise on contacting the factory.
I have now at least (I hope) fixed one of the problems the non working speedo, it was the 5amp fuse to the dash panel that was blowing and I have managed to trace it to the power line for the drivers seat belt light. I'm not sure how it was supposed to be stowed but it is quite long and was trapped in the seat rail under the drivers seat.Fixed out of harms way with gaffer tape.I'm no mechanic but I guess there is something to say for 44 years an RAF radio fitter and TV eng.
