Laney,
Thanks for the pointers - I will follow them up and make whatever decisions I feel are correct about the possible supply of the speedo cable.
Nunchuckhamster,
Laney was only trying to help me out with some pointers as to possible parts sources. Please do not take it out on Laney if you have a friend who is having legal dealings with any of them. Thank you, however, for your concerns.
All,
Lets be good and friendly about this - it takes more than one swallow to make a spring. - and I do need a speedo cable or my son's driver training will need to go on hold (I don't need a disgruntled teenager at present
).
