Windshield rubber gasket needed '64 Valiant

I need a windshield rubbber (gasket) for a '64 Valiant ('64 Dart will work.)

They are on back-order at Steele. and Steele says their supplier (a company called "Precision,") is re-tooling their molds, and they have NO IDEA when the process will allow a startup so that more can be manufactured.

We're screwed...

Anybody got one I can buy?
