My solution to this problem was to drill out the rivet holding the wiper to the arm and replace it with a standard new one. I drilled suitable holes in the new one and used pop rivets on the right hand one.However I had to use a nut and bolt on the left hand one due to the bulk of the double arm (I couldn't get the rivet gun close enough) I did this about 10 months ago and have not had any problems.
