Scamp vs. Valiant
Ok. Here's the real deal:
The Scamp and Duster are both Valiants .
To prove it , just check their VIN numbers. You'll see the letter "V" in the VIN numbers of both.
That "V" stands for Valiant (just check any online VIN number translator.)
If you still don't believe it , go to Google and enter this: "1971 Plymouth Lineup", then click on "images" . You'll see that The Scamp and Duster are both part of the VALIANT line .
The Scamp and The Duster ARE the two-door versions of the Valiant.
Both cars are a part of the Plymouth VALIANT line. I know....I have a Valiant Scamp.
