Demon front end conversion. INPUT??

If you visually strip the 70& up Dart/Demon/Dusters/Scamps/Valiants to the bare unibody up front, they are the same (with the exception of some mounting holes).

Regardless of whether they were 108" or 111" platforms, they shared a common cowl, and front unibody.

In 70, Dodge had the restyled Dart. Plymouth maintained their Valiant, and introduced the Duster. It was different from cowl back. The front clip was same as Valiant.

In 71, Dodge cried and got the Duster backhalf, and used the Dart front clip - Demon. Plymouth wanted their cake and got the Dart backhalf and used the Valiant front (Scamp).

73 and up Dart/Duster/Valiant/Scamps fronts are interchangeable as a unit since they have different designs to accomodate the legislated crash bumpers.

The key thing is that for both hardtop and fastback models, the lines at the cowl and on doors is the same, so they are easily changed.
