Roof rack plastic part number

[Cryptothedog]

Does anyone know the part number of the plastic cover/trim that hoes over the stock roof rails (see attached pic)? Also if anyone can point me to some documentation on how to fix that would be great. The car wash damaged it.

I tried online and there is a link to my 2017 yukon to give you an idea. It looks non serviceable from what I can tell - you get to buy the whole side.
