Borrowed from some Brethren over on earlyvaliant,org. this is for Valiants, but should be 95% correct for a Dart too.
There are five main areas to decode on a fender tag: the SO, NUMBER, BDY, TRM, and PNT.
SO and NUMBER go together as the Shipping Order number. It consists of a 4 digit planned delivery month/day code, then a plant production sequence number.
The date is decoded as follows...
JAN...1,FEB...2,MAR...3,APR...4,MAY...5,JUN...6,JULY...7,AUG...8,SEPT...9,OCT...A,NOV...B, DEC...C.
For example: June 23rd looks like this...623. October 3rd looks like this...A03.
Next is the BDY or body number indicating the model & body style.

Want to know if it's a Formula S? On the fender tag of a 65 Barracuda, look for the 'ABC'.... under the AB will be a '31' for the 273 4bbl 235hp engine. Under the C will be a '2' for the formula "S" package. The car should also have a tach in the dash....
