Well, do I feel stupid? I, for some reason, thought that nobody that we know of was making the wood for the wide bed, but after Mr. Tube mentioned Snyder's I looked in their catalog and sure enough they sell the sills on one page and the rest of the wood on the next page. Then I looked in Bratton's catalog and they do the same thing. Well, now we know - all of the bed wood is readily available! Thanks everyone!
