Found "body in white broascast"

Removing the interior of the notch today, i found an interesting piece of factory paper. It says "body in white broadcast" at the top and has the following data. body type VL41, engine 21, trans 5, tire code 225, date A27, number 00474, axle 2, trim code L4B, paint color WW1, inner dr E, Sequence number 032547. This is in addition to the two pieces of documentation I found under the back seat springs 3 years ago. I have already decoded the Vin # so I doubt there is new information here though-------
