[442w30]

The VIN should begin WM23(engine code)1. Previous Chargers had 29 as a bodystyle, but it became 23 in 1971.

Also, the 340 was available midyear, so the available engines are H (340), N (383), V (440+6), and R (426). The 440-4 was not available on the Super Bee but apparently around 26 were built. This is coded U.

Hidden headlamps were optional. So were rubber bumpers, which were not available with the former. If the latter were ordered, the car received R/T segmented taillights.

Hopefully this helps!
