Duster quarter window seals

Is there really a difference between 70/72 to 73 up Duster quarter window seals? Some places say there the same from 70 to 76 while others say 73 to 76 only.Also,there are at least two places that make these,anyone have an opinion on who make the better one? BTW,my car is a '72 Duster. Thanks for any input!
