On the door that came with my station wagon the rear wiper (fancy I know) has an arm with a wiper fitting I have no seen before. Rather than the arm being hooked to slide work as plastic clip into the end of the arm has a pin that clips to the wiper. Is this normal or has a different arm been fitted to the motor?

I managed to fit a new wiper which was the important part. But I have not tested the motor yet just didn’t want the metal arms of the old one vibrating and damaging the glass

Mine isn't like that.
All of the wier arms/blades are the same on my 90

My old one wasn’t like this either. Thankfully it took a normal wiper as they have the pin hole drilled. But not a fitting I have come across.
