Bears63, 1953 panel and Tim, thanks for the replies and encouragement. Tim, I found the metal strips that go between the 2 cardboard pieces under the side windows. However, I think I might go with a single upholstered plywood piece instead. The cardboard parts don't come close to fitting correctly and the screw holes are way off. The trim channels that go over the cardboard pieces are about 1/4 inch too big all the way around. I am slowly learning that repro parts can be a total waste of time and money.
