There is always a possibility its a real shaker car.Look at the N96 on the Fender Tag,if you have the broadcast sheet look under N column then look for the 9 and see if 6 is under the nine.Then look at the body of the car to see if there is a hole drilled in for the shaker cable.Next look to see if you have the under padding from the car and look for a factory punch hole so a shaker cable could go in it.I have seen 1970 Challenger that did not come with a shaker that have had the hole in the fire wall from the factory,just a mistake at the production plant,but there are a lot of mistakes,remember they were only cars back then to someone working on the line.I have also seen options on the fender tag and not on the broadcast sheet and vise versa.
