Approx 100nm to do a wheel nut up more than tight enough, so pretty damn tight for the first quoted torque figure!
Due to fact that I have had a bit of spare time I have finally finished my gearbox rebuild, gearbox is in, exhaust is on, rear diff is back on with the back lash slightly improved. So hopefully tomorrow I can take it for a test drive and see if everything works.
Well done.

Took it for a quick drive today.
The throttle was sticking a little bit at first.
The gear box is sounds better through the gears and it all works, the backlash I had in the diff was much improved.
The only downside is that the gearbox is still noisy while idling unless I press the clutch and the noise goes away.
Not going to worry about that at moment.

Copper bush? If it fits in the end of the crank through the centre of the flywheel it's a spigot bearing and should be something like self lubricating phosphur-bronze - copper is too soft and will wear away very quickly.
The Haynes manual certainly mentions the spigot bearing with early ones requiring lubricating and later ones self-lubricating.
In the Z world people more commonly refer to it as the pilot bearing but it’s the same thing.
You can buy roller versions of the same for racing applications but they do need servicing so not great for a road car.

My first reaction was also clutch throw-out bearing, but the “spigopilot” bearing makes sense logically.

has some clearish advice on telling spigot, release and input bearing noises apart.
TBH I'd always understood the release bearing to always be the guilty party. I think I've learned something!

That link suggests the gearbox bearings are at fault then.
Well I think it might be the input shaft bearing.
