Mopar Fender Tag Decoding

Chrysler “fender tags”, located on the inner fender in the engine bay, can be a valuable source of information. The following is a description of fender tag characteristics grouped by their similarities. As a general rule, fender tags are read from bottom-to-top and left-to-right.
The fender tags of 1962-66 cars are laid out in a very similar fashion. The scheduled build date is under the left portion of the “SO NUMBER”. The number under “BDY” (body) represents the car line and model, which is the same as the first three characters of the V.I.N. The number under “TRM” is the interior trim code, while the exterior trim codes are found under “PNT”. Sometimes the paint and trim codes are transposed, but this should be fairly obvious. The row of uppercase letters (4th line from the bottom) represents option categories. A number under any of these letters defines an option in that letter’s category. The row of numbers at the top of the tag are not yet known, but are thought to be routing, shipping, or gate information on 1962-64 models. For 1965, these numbers may represent option information in addition to routing information. Also for 1965, “A”, “B” and “C” take the place of 10, 11, and 12 in the production date for October, November and December. In 1966, the row of numbers at the top are replaced by a row of lowercase letters, which are another row of option categories. A number under any of these letters represent an option in that letter’s category.

For 1967 and 1968, the bottom 3 lines are changed completely as compared to earlier tags. The bottom line at the left starts with 2 letters and 2 numbers which identify the car line and model (same as the first 4 characters of the V.I.N.). This is followed by a 2-digit engine code, a 1-digit transmission code, and then a 3-digit tire code. Next is a 3-digit build date, followed by the order number. Moving up to the 3rd line from the bottom, numbers 1 through 8 appear here, which denote categories. A number listed under any of the category numbers defines an option in that category. To the right of the 1-8 numbers you will find “AX” for axle, “TRM” for the interior code, and “PNT” or “PAINT” for exterior colors.
Continuing to the right, there is a grouping of letters “UBS”. The “U” is for upper interior door color, “B” for buffed paint and “S” for the stripe or accent color. The codes for these are listed directly below (on the 2nd line from the bottom). The 5th row from the bottom is a row of upper case letters representing option categories. At the top of the tag is a row of lowercase letters also representing option categories. A number under any of these category letters defines an option in that letter’s category. For information on decoding the option codes, see our selection of books by Galen Govier in the Literature section.

The 1969 Lynch Rd. plant fender tag is somewhat unique compared to other 1969 tags. The bottom row, to the left, has the 4-character car line and model code (same as the V.I.N. first 4), followed by a 3-character engine code. These are followed by a 2-character transmission code, then the 3-digit build date and the vehicle order number. The 2nd line from the bottom starts with the exterior color (usually 2-characters) followed a 3-character interior code and a 2-character upper interior door color code. Above these codes are a few selected codes, usually abbreviated actual option codes. Lynch Rd. tags typically list very few option codes, regardless of how the car was optioned. The 5th line from the bottom usually contains 3 groups of 3-digits for the engine, axle, and transmission build codes. The top line is not yet known. In 1970, Lynch Rd. tags became more like other plants, but still retained the 3 group, 3-digit engine, axle, transmission codes on the 5th line from the bottom.
