Yeah, indeed
If i put the plastic windscreen on the underside and i move the wiper than the wiper goes to far and the plastic would brake,so i only testet it without the plastic and thats why i asked for more info .

Can i make the wiper point more to the middle or would this just brake or just not to do ??

Otherwise i gonna get myself such a Fiat uno wiper motor and wiper arm.

The bottom ball joint has moved closer to the pivot point, but no good enough

I let you guys know (and girls )
