Aspen cowl hood?

I went through this with my '65 Dart so I spent a few minutes searching.
Man........good luck.
Try a " wanted " classified ad here , Moparts and racingjunk would be my next step.
I went through Showcars in Toronto .....if he hasn't been shut down yet , he probably lists on for your car.
If you can wait 18 + months for it to ship , that might be one avenue......but the quality is poor at best.
I found a used A&A that was a great piece.....not cheap but worth it.
You will eventually find one , but it will take patience.
