We have the Technology...We can rebuild her...
Been there done that. I was lucky and someone sent me the whole panel. I thought about piecing it in but ended up welding the whole thing in. Looking back I think it was the way to go. Try Jerry at Euroeast. He parts out P-cars. When I did my car Restoration Design didnt have the panel available new but they were working on it. Hope that helps. May the force be with you.
