find-your-muscle-car: 1973 Duster 340 at 75-80 Raceway in Maryland

Taking a 1973 Duster 340 decode as an example, here's what Vehicle Identification Number, or VIN, can tell a potential buyer about this Mopar. It is followed by a breakdown of the codes on the metal fender tag that is found secured to the fender under the hood on most American muscle cars. You'll see that very detailed information is provided, right on the car itself.

These two pieces of information validate the integrity of the Duster as being a real, from-the-factory muscle car. This is must-know information for a muscle car buyer.

Different websites may provide slight variations in the decode so if you are the obsessive type you can check your VIN and fender tags at more than one site.

For example, we provide a source for Mustang vehicle decode information and other vehicle marques as well.

A sad but important note: dishonest muscle car sellers will replace the fender tag on a base model car with a fender tag from a high performance muscle car in order to sell it at a higher price. In 1973 Plymouth produced a large number of 6-cylinder models in the same body style. Sometime in the last 30-40 years, a previous owner may have replaced the factory 6-cylinder with a V8 from another car and re-painted it to look like a 1973 Duster 340 high performance model.

As a general rule, there's no problem with this, as long as the modification is clearly stated by the seller and you know what you are buying. We replaced the original 318 in my 1972 Dart Swinger with a 1969 340 that has more of what you buy a muscle car for. In the future we will add bumble bee stripes and other cosmetic changes to get just the look we want.

There are ways this can be identified, by checking matching codes on other components of the car for example, but most buyers won't have the expertise to do a proper verification. If it is important to you, and if you are paying a premium price for a rare muscle car, take the time to have the car appraised by an expert.
