Sorry about the JTR and JCI info. I was some time ago and I got the info a bit confused.
I figured I was too old the try laying on my back and juggling a transmission on my chest and knees, so a mechanic friend did it at his workshop.
Absolutely no dramas. He removed the transmission first and then the bell-housing.
Had to replace the flywheel, clutch and pressure plates, and slave cylinder as a complete package.
He had trouble bleeding the system so I have the car back home and will fit a new M/C when one arrives.
