Help with a Seal

[Trenton]

So I have a leak on the passenger side of my truck. I've traced it to the seal that goes all the way around the top of the cab. It's the one that starts where the top of the fender meets the door and wraps all the way around the end of the top of the back door. Does anyone know where I can find this seal? Ive tried gmpartsdirect.com, rockauto, and summit and i can't find this specific seal.
