Rockwood-
I made my own door panels with the vinyl strip on the bottom using the old stainless strip that separates the fabric from the vinyl (that was a b**** to do, but it paid off and looks original). I used 1/8 inch thick pressboard that I got from Home Depot with white vinyl backing to keep any water or moisture from penetrating through and warping the panel. I don't know what route you are taking, but I went original classic style. There is a fabric shop near where I live in Rialto, California that has the "close to original" material that was used on the doors and back of the seats. It's soft to the touch, too. As far as the seat interior...I had to scout around for 40's style striped material. The Le Barron Bonney material was way out of my affordability, but I didn't want to resort to "new car" material either. I got the headliner from EZ Boy Interiors for a very reasonable price and it fit like a glove, not to mention, looks like the original stuff that was there before. They have assorted colors, too.
