76 intake gasket?

[Offcenter]

The rectangular rubber gasket that fits between the air filter box and the top of the engine on my '76 GL is ruined.
(crushed by some previous owner who didn't take the time to fit it properly. )
Anyone know who I might get one of those from?
or does anyone have one they don't need in good condition?

Thanks everyone.

I see 'em on Ebay pretty regularly. I bought one a couple of years ago for 5 or 6 dollars...

Thanks Steve. I'll take a look there.
