As I found out at DMV you can only keep blue personalized plates.
If they are sequential plates they cannot be transferred to any other car.
I tried to switch the blue plates to the Challenger, but because they where not personalize, I could not.
I was told I could keep the blue plates and as long as I have a registration showing that they went on the Dart at one time, I could return them to the Dart if I ever give up the 340 6PK plates.
