Ford Ka Mk2 wing mirror fitting

[Gwronyglyn]

Hi,

 

Just got a used 2012 mk2 ka and needed to replace the old passenger side mirror due to scratched glass and plastic housing, discovered in the process that the top clip on the original wing mirror was snapped off and was held with glue. I've bought a new unit which includes the wing mirror and exterior trim on the ka but having trouble getting it to sit flush.

I'm able to attach it by the three bolts accessed by removing the indoor door pillar trim piece but the top part of the exterior trim still sticks out and it doesn't seem like the clip is connected to anything. Photos attached.

 

Wondered if anyone could offer some help.

 

Cheers
