Keith,
The bare panels are available from suppliers like Legendary, but the shape is not 100% correct.
You can buy material and cut them to the same shape & size as originals. I have an original set that
I could make patterns from. The headliner and headliner material is available from SMS in Oregon.
They are the only supplier that I know of that has the original silver metallic fabric.
I need to dig out the originals I have and post pics. That will give you an idea of how much extra to
leave on the edges. The headliner material just gets glued right to the cardboard backing. Some
handwork is involved, but nothing mysterious. The ones you see in the pic were made as described.
