I finally found my VIN on the frame of my 57. It was right where everyone said, under the #3 spark plug on top of the frame. I couldn't see any letters at all because it was covered with years of paint but I did notice a slight dip or dent in the frame. After scraping off the paint there it was. If anyone is interested I would be glad to mail pictures to your email
