To my knowledge, the number plate on the frames never match the VIN plates on the dash and door opening (although they seem to be close on many cars). Perhaps they meant them to match at one time, but in the end, none of the cars were assembled that way. Also as far as I know, there is no record that keeps track of what frame number was used on which cars. Unless anyone can say otherwise, it is safe to assume that the number on your frame is completely arbitrary and has no relevance. Walt Tampa, FL
