A friend of mine just bought a '74 Dart as a restoration project (yes, here in Czech Republic, it makes sense to restore a four-door 74 Dart) and he's got some trouble decoding the fender tag - he used online decoder here

It says that J42 option should be the pistol grip - but it's an automatic Dart. Also, it says bench and the car has buckets - does it mean the seats had to be replaced, or it could be a mistake (from the "pistol shifter" bit it seems that the decoder was developed for something other than a '74 Dart...

Here's the fender tag:


And if anyone's interested, here's the whole car.
