They should be available. That's part of the beauty of Chevy engines, they made a lot
of them for a long
time and lots of parts interchange.
It's like an o-ring with a slightly rectangular cross sections. Some people call it an o-ring, but to me that implies a circular cross sections. Maybe just me.
On edit: Vinnie posted just before me. He's right again.
You really shouldn't have any problems getting one, just take your adapter in.
(Taking your old parts to the store with you is always a good idea.)
