Looking for the two spring washers that sit under the screw cap to hold the wiper arms on. #11 in the picture below.

Is this a special size? Regular washers don't fit inside the little recess in the wiper arm.

Thanks.

Not special to the best of my knowledge. 99 % of all cars are missing them though.

We buy all the small wiperarts at our local Porsche dealership. Other places carry some of the parts but the Porsche dealer is the only one I found that has them all.

Ok - thanks guys.
