I didn't see where he said the title was different than the door plate. The title would most likely not show the body serial number unless it was retitled to show that instead of the engine serial number, as was done in most states. In California, at that time, the title only showed the year first sold, not the model year. The truck could have been first sold in 1952 with that build date, and would have been registered as a 1952. It would not be worth the trouble to have it retitled as a 1953 if that is the case.
