Thanks! Don't suppose you know if it's the same for the ignition?

The ignition lock changed from Simplex to Bendix (Iirc) at Rp 6078 and the number of leads out of the switch also changed.

Simplex type has 1 grey + 2 black connectors
Bendix type has 1 grey + 1 black + 1 brown connector.

Afaik, physically the locks are the same, so with either changing the lock barrel, or switch, or a bit of wiring, one could make either work.

Thanks for the info! I take it the lock barrels is just held in with a torx bit it something so that it'd just pop out and go in the other?

Cut the ty-wrap binding the cables to the column, insert the key, turn to position 2 (iirc), depress the spring loaded pip and pull the barrel out.

May I ask why you want to change the door lock? Other option would be to modify the original locks to accept any sx9 key.
