Make a solution of water and a little dish washing soap and apply it to the rubber nuts before pushing them back through the mounting bracket. (This solution will also help you get the nuts back onto the windscreen.)pauljo said:I push the rubber nuts through the screen, leaving the rubber flange on the outside of the screen as it is supposed to be. I stick the screws into the nuts without tightening them and push on the screws. This makes them go through the holes easier because it helps straighten out any buldge in the rubber nut left from when it was previously tightened. Then, with the rubber nuts and untightend screws (and washers) in place, I position the screen and push on the screws again to force the rubber nuts through the holes in the mounting bracket.
Also, you will not be able to tighten the rubber nut with the screw if you do not engage the threaded brass insert inside the rubber nut just a turn or so before you mount the windshield back onto the bracket.
