If it is in fact any early 47, the headlight buckets are obviously the same as a '46 and should be fairly easy to locate. I have heard people in the same situation go out a purchase a junker of the same vintage just to get the vin plate and clean title, maybe even a few parts needed too (headlight buckets??). I am not advising any sort of unlawful activity, I'm just saying, it has been done......Also, when I had my '46 in a million pieces, I never saw any numbers on the frame anywhere. Did they stamp the frames with vin numbers back then? Even if they did and you went to register the truck with a different vin plate would the dmv even know where to look or make the effort? When I register my truck, they took the numbers I had and the title and I was out of there in 15 minutes. I also registered the truck with vintage '46 plates and was surprised how easy the whole process was, especially for the MD.
