I have a '45 GMC with a wooden bed. I was convinced that the original steel bed was replaced with what is there now. I am not so sure now. When did GMC stop using steel beds? Would it have made sense that a War truck would have used a wooden floor to conserve steel?
I have seen Carter's offering a repro steel bed for GMC's in the catalog if you're interested. My local steel supplier can do them as well, with original style ribbing.
