OK....another decoding question.......

I have only seen L42 for 2 dr hardtop and L45 for convertible and L76 is a station wagon.
L452 in vin# in 1965 indicates L = Dart V8, 4 = Dart GT premium, 5 = 1965 and 2 = assembly plant Dodge Main ( Hamtramck).
Just to clarify, I was talking about 1964 and quoting D/Dart man's fender tag he posted as an example. Sorry for the confusion.
An example of another 1964 body code plate for a Dart GT 273 V8 for comparison. My top line does have an 8 in it and the middle line cannot be decoded with any sense with online decoders. It just doesn't match anything on my car.
But the number 5 under the A matches the authors V8 Barracuda body plate. So there is that.

The bottom line is easy to decode.

Accurate 1964 "early A" decoders may not be available.
It may be my California plant build that makes it more difficult.

Chrysler Historical came back with a "no record found" on my car.

So your Dart is a L445? on the VIN tag?
