Oil pan gasket replacement

[97z28]

I've got a 1997 sho, does anyone still produce a oil pan gasket replacement? I've had good luck with the dealer on a lot of parts for this car but they can't get their hands on one of these. Nothing in the aftermarket world either.

Just got the pan off, I realize now it's an rtv pan. No gasket, incase anyone was wondering
