Wiper blade fitting - 156
I've just replaced my driver's side blade with a Bosch spoiler blade, but there is a right-angled metal clip on the arm that sticks up and doesn't seem to fit onto the blade - it just presses against it.
I know I should have looked where it went on the old blade, but didn't even notice it until fitting the new blade. It's not affecting the blade at all, it just looks weird.
Any suggestions? Is it part of the original arm or just an add-on that came with the previous blade?
