Click on the link below and browse through the various links for 1972 Plymouth. I find it to be a very useful source whenever I have questions like this.
However, as the previous posters have said, never say never, as Mopar historically did a number of customer request items that lead to some interesting variations and “one if none” examples that pop up now and again.
As a model builder, this gives you a bit of artistic license to create a story, for example maybe the customer wanted to buy a Satellite Sebring but wanted a Roadrunner hood and stripe and the dealer was happy to do it. Or maybe an executive wanted this configuration for his personal car and knew all the right people to talk to at the factory to get what he wanted. Or…?
