Hi all, time to confirm a debate. The waist seal clips you can buy today (from Moss and elsewhere aren't just "U" shaped. They have the "U", and they have a small clip lower on one side. So... which part attaches to the rubber waist seal, and which part attaches to the metal lip on the door? I've seen Youtube videos that contradict each other. The small lower clip won't firmly grip the rubber seal without crimping it. Who has the definitive word??
