Decoding your 1973/1974 Plymouth Fender Tag

The fender tag is located under the hood on the driver's side inner fender. The tag contains codes that pertain to how the body or the car was initially assembled, and some of the options that were installed on the car. Not all options are listed on the fender tag and each Assembly plant had a different layout for some of the codes. Typically, tags are read from bottom to top, left to right. If a car was heavily optioned, it might have more than one fender tag. 

Individual codes are found at the bottom of this page.

St. Louis, Missouri Assembly Plant (seventh code in the VIN is a G)

Windsor, Ontario, Canada Assembly Plant (seventh code in the VIN is an R)

The Windsor fender tags are laid out almost exactly like the St. Louis tags, except for the Radiator Support size code. The radiator support size code shows up at the beginning of the Option Codes section of the tag, versus just before the END code on the St. Louis tags. If your St. Louis car does not have a radiator support size code, then it came with the standard sized radiator support - usually the 22 inch support for Plymouth B-bodies.

Lynch Road, Detroit Assembly Plant (seventh code in the VIN is an A)

The Lynch Road fender tags are significantly different when it comes to what options are on the tag, and where those options are placed. Additionally, there are extra codes across the top of the fender tag. The first two groups of codes are gate series and line sequence codes. An excellent article that explains what these codes mean can be found here: https://maxwedge.com/articles/lynchroad-gate-line.php   The remaining codes are engine, transmission, and axle assembly codes. These assembly codes are also found on the broadcast sheet from all plants, and can be found at the bottom of this page.

Color Codes for Body, Top, and Inner Door:

Vinyl Top Codes:

Interior Codes:

Scheduled Production Date (SPD):

This is the date that the Assembly Plant ESTIMATED when the car would be rolling down the assembly line. 

First digit is the month . 1 = January  /  2 = February / etc etc / 9 = September / A = October / B = November / C = December.

The next two digits are just the day of the month. Example: B15 would be November 15th, and 315 would be March 15th.

Vehicle Order Number (VON):

This is usually a 6 digit number that corresponded to the Dealership order pad on which the vehicle was initially ordered up. This allowed the dealership to track an order until a VIN was assigned to the ordered vehicle. Chrysler did assign some vehicles with a special VON in order to track the quantity of these vehicles. Typically the special VON had a letter in the first digit. Below are some of the special VONs that I have come across so far.

Country Specification Code:

Remaining Option Codes:

This is by NO means a complete set of Option Codes for the 1973-74 B-bodies. If you have an option code that appears on your fender tag and is not listed here, please pass along the info so I can add it to the list. Thanks!
