I have had my tailgate bar for several years. I had the back window unzipped and the bar was loose. I was going along and a gust of wind pushed the bar outside of the truck and it was floppin around, so I pulled over to put things right, only to discover the rubber seal was gone. I have looked around and can't seem to find just the rubber weather strip that goes on the bar. I would really rather not buy a new bar just to get a new seal. Does anyone have any suggestions on where I would be able to find a replacement, or if they are even available?
