Are you talking the very front extensions by the headlight buckets? Never knew this.
Long time back I almost went with a Demon as a contrast to the ever so more common Dusters. Though I love the Dusters and believe the Dusters are lighter by a few, I can understand the pickings.
I know a guy who's lightening a 73' Dart but in all the wrong places. I cringe when I look at his HEAVY bumpers and he is looking at taking a small bracket off the rear instead. To each his own though. At least he's having fun as we all are.

Feather Duster linings is what can be rather trick, though limited to certain years.
