I finally ran out of those "small" jobs and it was time to fit the engine. After a few attempts, and much swearing I managed to get gearbox to mate with the engine. The clutch was aligned, but the spigot bush was obviously a perfect fit, so the gearbox needed to be perfectly level to slide in. Everything else was prepared and ready to go including, new bushes on the gearbox remote new gearbox mounting rubbers, and new clutch release bearing and arm (just hope it's all correct as I really don't want to EVER separate the gearbox and engine EVER again ;-)
We lowered the engine into the engine bay with no trouble at all (thanks Michael), until it became obvious that the engine mounts would not fit. After much measuring and more swearing I realised (OK Michael did), that I had the engine mounts the wrong way around - whoops!
