1976 Plymouth Valiant/Duster for Sale

If it's a fastback style (nova for the chevy challenged :thebirdm:) it's a Duster.

I think that's why many are confused. There's the Dart style xx23 (scamp) then the Duster/Demon/Dart Sport style xx29 for the first four of the VIN.

Sounds like you have a Duster.

I may have confused you... A Scamp is a model in the Valiant line, just like a Duster. HTH
