The 1976 feather Duster also the Dart Lite were factory lightweight cars. Do a google search on Plymouth feather duster or Dart lite

Sorry.....when I think of factory light weight , I think of this.

When you start talking Corning glass , aluminum bumper brackets , aluminum fenders and bumpers etc. etc. , then you are talking bidness.

The Feather Duster and Dart light were attempts to improve fuel mileage , not performance.
While the aluminum hood is nice , you'd have to be a full on retard to cut one up for a scoop.
