>"The issue of blade touching glass properly for its entire travel, and then flipping over for the return trip, requires a mention. Angling the wiper to the arm alters the perpendicularity of the blade to the glass, since we are in 3 dimensional space. This means that the wiper arm shaft needs a slight CW rotational tweak, in order to prevent the blade being driven, edge-first across the windscreen (with attendant chatter) and never toggling over. It is not hard to do, and with a couple of smooth-jawed pliers, there were no marks in the SS arm, and the twist is not really too noticeable. Point is, that the installation looks good and works very well.
