I just picked up new wing mirror glass from Renault and the glass has a black surround like most modern cars, but my original didnt (just glass). It has a small black plastic rim that protects the edge of the glass about 1mm thick.
Is the Williams glass different or have Renault just altered the manufacturing process?
Shall i keep it or take it back? Not sure youll notice once its on the car but dont want to fit non williams glass either.
