Good job to do, I've got the same as the windscreen guy snapped the bolt off! The trim that runs down the side of the windscreen has to be undone, the rubber one thats part of the door seal, wipers arms have to come off too, by then hopefully you can slide the bottom trim to one side. then just follow your nose, the little plastic clips can then be removed and replaced in the strip. sorry guess this won't have helped to much. Think there is a tread some where.
