These are good reproductions of the originals for your American Sunroof Corporation Golde Sun Roof. The roof opening seal is 89 1/4" x 3/4" and the seal that affixes to the rear edge of the roof panel measures 42 1/2" x 3/4". These have the correct aluminum inner core with rubber bead, wrapped in the correct felt textured, black material. These are made by the original manufacturer in Germany and will fit all Cougars equipped with the ASC sunroof. Very hard to find seals at a reasonable price. This same basic roof was available on the Thunderbird, Lincoln Mark III and in some rare cases Mustang, Australian Falcon and others.
