The weatherstripping on the sides of the windshield of my '68 convertible are tattered on the outside edge, but still seem to seal against the door pretty well. They just look bad. I purchased replacement rubber that is supposed to be the best replacement brand, but upon inspection, they don't appear as "beefy" as the originals at the top where the roof mates when the top is put up. I think the manufacturer is SoftSeal. I haven't replaced them yet. The installation instructions are a little vague and they don't mention a metal clip that is about two thirds of the way up on the pillar. Does anyone have experience with these replacements? Any installation advice? What about that metal clip? Much appreciated.
