Default Catalytic converter gaskets?

Does anyone know where I can source some new catylitic converter gaskets? The upper ones (between manifold and cat, NOT between the cat and mid-pipe. I've checked Auto Zone, Rock Auto, Carson Toyota, etc, all I can seem to find is the flange gaskets, and the cat-to-mid-pipe gasket. Thanks!

If you could provide the year of manufacture I will try and help with the part numbers. I assume they are not for a Subaru Impreza

Default Gaskets at NAPA

I recently purchased a good quality set of gaskets (3) for bank 1 cat at NAPA in Seattle. All three totaled about $25. out the door.
I have not seen a cat replacement photo set or video on this site so I will post once the project is complete.

This is relative to my 1999 RX300

Usually, IF NAPA has it, it will be a good quality, I love their wiper blades... silent and long lasting.
