A massive shot in the dark, but would anyone have any gearbox engineering drawings for the M20?
Anita kindly picked all the hole centres for the inner cover, and the numbers don't seem to make sense.
It could be machining inaccuracies of the time or just strange numbers.
Along the same lines if any M20 engineering drawings exist I'd happily pay for copies to be made.
The shaft centers are the first ones that nibble at me, but the operating radii of the selector forks bite, they are so far out from each other. I really don't want to check every casting I have here Ian.
