I've done a lot of reading on the forums, but this is my first post.
Matto, I owe you big time. What bloody incredible guide! I'm no mechanic, but I always do my own repairs - I couldn't have replaced this part so quickly and efficiently without your help. I really enjoyable job this was, and really satisfying to finally have the problem solved.
Fitted the new lock to my passenger side... now I need to find a new lock for the drivers side! Same problem.
Thanks again
