Sorry to say cerealsurfer, but there is no fettling planned with the gearbox.
I would not dare to do that to my new Morgan (or even any other car!)
If anyone ever sees me with a spanner in my hand, RUN!
The reason I asked is that I bet on a Mazda MX5 gearbox. Mazda is correct, but I'm pretty sure now it isn't from the MX5. Seems I have to buy my neighbor some pints...
