I've just done this with my Ghia 2.0l.
You have to change everything from the crankshaft to the wheel hub/knuckle (exclusively) including gearlever and cables.
A few minor niggles as well such as clutch hydraulics, heater hoses, reverse switch.
Oh, also as the VSS reads the FD pinion rather than a dummy speedo drive gear, the speedo overreads x3. So you need a re-calibrator. I used a SpeedoHealer, but that needs some extra bits as its designed to work with motorcycles. According to the manufacturer cars are abnormal!
