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.
