Why were they even worried? Back then all bumpers did was protect the car from serious damage in a light impact. They didn't ad any safety to the occupants.
i saw daytona's and superbird's go to the car actions years later because they would not sell . here in california so sf bay area . the cars had a few miles on them , so they were 3-4 years old . sold them at the used car actions .
Actually, the Daytonas sold out before production started.
Birds were another story, with 1970 being the start of a recession.... Plus they had to build 4 times as many!
It seems the Charger Daytonas were not legal and registered in Md., Plymouth might have considered their bumper Strip sufficent which it was not. DC seemed to have had the same rules.
At least one car was registered in 1969 is still considered to be in the Hands of the original owner. Most or all others are supposed to be bought back and redistributed to Fla. to some sources. And there's the Story about at least two 70 Daytona Chargers but without the rear window treatment, one registered originally in MD to a Bethesda Hospital doctor by the Name of Jackson with some bumper cobbled up for Registration back then, now residing in Kansas.

There were 2 Superbird's in the Aberdeen area in the 1970's. Alpine White and another was limelight Green. Both owned by soldiers and titled and tagged in other states. I knew the guy (1977) with the white bird and he said the locals stopped him a couple of times and he had all of the legal documents. They were more interested in what was under the hood and never said anything about the bumper. I had a beat up 1971 GTX back then that I ended up shipping to Germany when I was stationed there later that year.
