I have recently taken off my door mirrors as they were loose and flopping around. I have the bits as below in the picture (1 & 3) but not 2. I think they were loose as part three was on top of the door going through the holes. So on the drivers side, I put it inside the door and screwed part 1 to it. This created a far better fit and now the mirror is nice and secure.
I have two questions:
1. Should I be using part two on top of the door (as a gasket) and fitting part one on top of it or if you have three and one can you discard two?
2. Part three has broken on my passenger door, does the mirror mounting kit come with it?
Sorry for the number one, two and three. It was the best way I could think of explaining what I meant, with the picture
