Amazing how the opinions about post-war production can come flying out of the woodwork. The bed in my truck is of tongue-n-groove southern yellow pine with no spaces for the metal an rows of carriage bolts fastening the bed down to the cross members. As stated before, my truck was made in February 1946 and just because the wartime restrictions were lifted, it would have no bearing on the actual availability of materials. In 2002 I lived 13 miles from the Janesville assembly plant and had the opportunity to ask an "old timer", former head of the union, and he verified that this practice was in place in early 1946.
