As others have stated there really is no way to document a "numbers matching" truck, or car either from that era. At least not a Chevy. Each series of truck and car had engines, trans. and differentials with serial number prefixes unique to that series, though. This 49 half-ton for example: The body serial on the door hinge post plate will have a 1 or 2 digit number followed by GP then another letter followed by 4 digits - like 21GPD1234. The original 216 motor serial number stamped on the little flat spot beside the distributor will start GBA or GBM only for 49 1/2 tons. The G is the year code 1949. P in the body number is 1/2 ton. A or M in the engine number stand for Flint or Tonawanda, respectively. May I recommend Keith Hardy's online resource here . Good luck. wink
