LS1 Flange gaskets?

Where in the heck do you get the gaskets between the manifolds and the y-pipe on say an '01 - '02 manifold? I have looked everywhere locally and nobody lists it, cant find it online either. All I can find is the gasket between the heads and the manifold.

We don't have Advance in Canada but those Felpro numbers should help. Thanks.

Seems to be about as expensive through the dealer as a local parts store. IIRC mine were about $7 each

Id recommend putting fresh exhaust studs in too, originals like to break, mine have and i regret skipping that
