3rd gen tonneau cover parts

HI all.

I have been looking and looking and I can't find the replacement part for the trifold oem tonneau cover . It would be the rubber cover for the bolt that holds the cover onto the bed. I'm not sure thats even a replacement part. I can sent a picture if needed. Guess my next option is to the call the dealer as they did replace my seals under warranty a couple years ago and I do treat the cover with UV protection. I'm out of warranty now though well bumper to bumper that is.

 

Think I found it after about 3 hours of searching here and the internet.
