All 1971 chargers built after October of 1970 have the gap in the vent on the hood!
That's not true with the Ramcharger equipped cars. I have pictures from a 2 owner 71 R/T, 50k mile, 6 pack, 4spd car. December build. Current owner has had this car since 1974, and knew the original owner. This car is original paint, except for a touch up on one fender.
The Ramcharger hood on his car has a solid row of vents with no break.
It's also a Lynch Road car, if that matters... It has some cool options too.
