Can anyone help me find this part?

Hi all! I'm having some trouble find this gasket for my 98 T/A. Is the small gasket that you put between the small pipe conection at the top of the exhaust manifold and the pipe that has the Air check valve related to the Secondary AIR system. I don't know the name of this gasket or a part number. They can't find it at the auto parts store. Anyone can tell me the name and/or part number? Thank you.

The gasket between the exhaust manifold and metal air pipe? I got some at the dealership a few years ago - GM PN 12553617. Assume the '98 is the same - plug the PN into gmpartsdirect and it shows a pic of it.

Thanks. I got them at the dealership.
