I've never been able to set my blades to just sweep the windshield. They always cross one side of the frame or the other. I'm thinking one of the pantograph types may be the solution. Does anyone have experience with these.
Agree. Just wasn't looking closely. The threaded part of the shaft is just for the nut to tighten against the superstructure. The arm itself sits on the splined end as shown above and the spring catch sits inside the groove.
