The brake and clutch pedals are now shortened and fitted. I had to mount them on top of a piece of box section to ensure they had adequate travel, and also to locate the clutch return spring.

But as usual, in solving one problem I've found another. The donor brake master cylinder is way too big. I don't know if I can use it, but on first inspection it looks impossible. I'll have to fit the engine and see what sort of clearance I have.
