WTB Edelbrock STR12 Crossram Gasket

[LSS&B]

I have a friend with a 1974 Dodge Challenger, 340, 833, Edelbrock STR12 Crossram Intake.
Upper Manifold Gasket gave out and the friend used a spare upper manifold gasket.
The person is trying to find another upper manifold spare gasket to have onhand, but Edelbrock says this intake manifold gasket has been out of production for 15 years.
Does anyone have or have a source for one of these Edelbrock upper manifold intake gaskets?

Might have to make your own gasket, doesn't look like a complex shape.

I always buy the gasket material in sheets and make my own gaskets when needed. You can buy up to 40"×40" gaskets sheets in various thicknesses from Champion Gasket here in Michigan. Or, they can even custom make what gasket you need if you send them either a sample or print. So will Cometic Gasket.
