How can you get classic car vin history?

Older cars built before the VIN became the standard do not have a VIN #. In the mid 1950's American automobile manufacturers began stamping and casting identifying numbers on cars and their parts. The vehicle identification number has become referred to as the "VIN". The obvious purpose was to give an accurate description of the vehicle when mass production numbers were starting to climb in very significant numbers. Research has shown that early Vin's came in all sorts of variations which depended on the individual manufacturer at that time. In the early 1980's the National Highway Traffic Safety Adminstration required that all road vehicles must contained a 17 character VIN. This established the fixed VIN system for major vehicle manufacturers that is known today. As older classic cars did not contain the VIN # is impossible to find a history.
