I had to shorten the length of the lever arm that attaches to the wiper. You will find that the wiper arm attaches to the knob sticking through the windshield cowling is bolted there. Take it out and you will see that there is a lever arm. I shortened it by around 1cm (I can't remember the exact measure). You will need to do this to have the wiper cover the whole windshield.
You will also have to reposition the wiper motor arm (the little one attached to the motor) so that you can have the wiper in the center of the windscreen.
Or leave it and have the wiper sit at the passenger side but still wipe the whole window.
This is how Mercedes do it, but they have a cam follower system so that it gets up into the corners.
It is a touring car look, or dtm, but the style has gone like pastels and neon. (You know, like the colors of your clothes
