Hello, the wing mirror on my mk4 astra got knocked off, the mirror itself fell out, so i bought a new one from halfords just to realize there is another bit missing and im unable to fit it back on, could you please help me out, as you can see there is some plastic bit missing and i cant put a mirror on, where could i buy this and what is it called?
