Using pabs' excellent fitment guide this mod took no time at all. I used flat screwdriver to prize the original wiper cover off and then undid the 13mm nut. Dropped the new wiper on tightened it up and added the new cover. See pictures below. I may loosen it slightly tomorrow as the trial run proved that the wiper made a bit of a squeak to imply it was too close to the glass. I koda dealer.
