The M47 with cable speedometer will be hard to find since the M46 went to 1986 and by then they had an electric speedometer.
Maybe in some markets the M47 was available earlier than here, I’m not certain but it’s easy to check for an M47 with the cable connection.
Perhaps in Europe you had more options for gearbox type, and you could order a 46 as well as a 47 at the same time
Yes they are configured differently regarding the clutch, left hand drive cars use a clutch cable, right hand drive has a hydraulic clutch system.
Easy to convert though
You might need to find one in pommyland for the clutch parts at least (fork, slave, master, lines, release bearing)
