Lancia Augusta in the workshop

I have a strong tie to this Lancia Augusta, I spent a lot of time working on it for its new owner when I sold it several years ago. He's now had it and enjoyed it for a year and wants me to have a look at a couple of issues that have arisen, the main one being the clutch. That will mean removing the gearbox but it comes out without removing the engine so should be straightforward. I don't want to do anything with the engine, I completely rebuilt it and the owner reports that it's running beautifully.
