vin question

1965 Codes:

L - Dodge Dart V8
4 - Signet, Satellite, Sport Fury, (Dart GT), Coronet 500, Monaco, 300L.
5 - 1965
5 - Los Angeles, CA

Last six digits are the sequence number (LA plant not gate) begins with 1 (place holder) and the next five numbers are plant year to date non-model specific total. i.e. The 70,528 model year car produced at the LA plant (I don't think this is a non-sensical or made up VIN ). To get the "replacement" VIN plate for whatever reason, the previous owner could have simply provided Cali with a copy of the title with factory VIN with proof of ownership?

This is the VIN decode asked for in post #1 it gets tricky without the fender tag

To further decode
1). With the vin (L455170528) and proof of ownership (do you have a title with L455170528 under VIN #?) you can request a build card from the historical society with decode. $45.00 or if you find the broadcast sheet your set for a further decode.

This will give you the gate and sequence # plus other info coded into the radiator support stamping.

Note:
2) A collector is not going to value the car with a non factory VIN Replacement Cali plate on the door jam no matter how much money you invest. The value of the car is the value to you. It received the replacement VIN tag 20 + years ago?

Stamping
3) there is a stamping on the radiator core support. This stamping contains some original VIN plus former fender tag code (build card) info. To tie everything together will require: a build sheet or a copy of the build card from the Historical Society (45.00 and luck/ patience...)

4) Does the radiator core support have a stamping? Mine is under an old anti-freeze label.

You have a unique situation complicated by the missing fender tag? This should not take away from your enjoyment of the car.
