I have a 73 Roadrunner 400-4 factory sunroof car and I have a question about the differences between a coupe and hardtop. My car is a RM21 car which I believe is for a Roadrunner Coupe. I was under the impression that coupes did not have rear windows that rolled down while hardtop rear windows did roll down, is that correct? The reason I ask is that my car does have power windows and the rear windows do roll down. Do I have my information straight? If so is this just one of those oddities that seem to creep up every now and again on these cars? Thanks!

P.S. This car is for sale in the for sale section if anyone is interested!
