How much does a 1973-76 Duster factory deck lid weigh (without any go wing cutouts and free of rust or bodywork)?

I just purchased a mint 1976 Feather Duster deck lid with the aluminum under side and put it on my calibrated digital scale. It weighs 30.0 lbs.
Just curious to see the actual weight savings for future reference.
