Wobbly Wing Mirror Pulled away from Boddy

[BaggyBoy]

Hi,

Recently someone crashed into my wing mirror and took the whole thing clean off. The garage fitted a replacement part, but it's wobbling when driving.

The mirror looks slightly pulled away:

I saw another post that says to tighten the screws behind the black triangle trim thats on the door. I have attempted this, however one screw (at the bottom) isn't there and it's instead a plastic bolt thing (sorry hard to photograph):

It's impossible to tighten this plastic thing. Because it is not screwed at the bottom it means the mirror is slightly loose and pulling upwards due to the screws only being at the top.

I thought maybe this was because the garage lost a screw or something, but looking at the aftermarket part, it looks like it is part of it:

Any help is much appreciated!

Thanks,

Who supplied the new mirror ? You or the garage that fitted it ?
