Superior Glass Works here in Molalla Oregon had a fire in the 'Glass Bay after hours. All of their molds and parts are gone. My one piece front end form my '37 Chevy Coupe was in the middle of the floor and still in the mold. It survived with a little crispy on the Cowl.
I have a good friend that has his work shop in his back yard. He has many metal parts late 20's & 30's primarily. I know he has a T shell and some other parts up on the top off his storage rack. I can call tonight and ask if he has a metal dash.
