Acrylic or Bakelite? What are they? Who currently is doing restoration of these pieces? Anyone still doing it?
This is a project just waiting for some younger person to take on. Every 38 Cadillac and LaSalle that has not had the dash replaced needs one. Should be a good 3D printer project. There are factory drawings floating around of most of the parts.
My friend is working on a 3d print of this. also, the original was a soybean based plastic. The heat was terrible on them.
I do have an original drawing of parts of this dash if that would be helpful to your friend. Just copy and shipping cost. It is a real interesting drawing. 30 revisions on it. They were having trouble.
