Hello guys.
It's been a long time since I last posted, but I have an issue with my door handle and would like some guidance.
The other week when we had some ice I can only imagine some damp got into my doors and then turned to ice and popped the little adjustment bit off the handle. I promptly fixed this on both driver's side doors front and rear.
I've always been told never to undo that little screw, but never really known why other than it'll drop into the door if you do... Now I know why you shouldn't undo it all the way

From what I understand I need to strip the door down and then there is 1 screw under the front edge of the handle which secures the rear mech to the door metal. Is that right?
I should be able to re-fit the locking C piece back to that mech and all will be well?
