A caution about using the numbers stamped into the trans.. Most old cars have had at least one trans replacement during it's life, therefore, the number would be wrong, in the good ole days nobody paid any attention to serial numbers, the only time the question came up was if the vehicle was relocated to another state..
During the 66 years I have owned my '36 I have relocated it to four different states, never a problem.
My brother has a '37 Ford 4dr which he bought while living in CA during the mid '70's. My brother decided to move back to Idaho after living in CA for twenty-eight years. When he had the serial number varified in Idaho they found that the serial number stamped into the frame adjacent to the steering gears did not match the title/registration.. OOpp's
