440 duster weight, 3440 LBS

My 75 was under 3100 without me, It had an all iron 451 except intake, 8.3/4, glass bumpers, aluminum brackets, all else was steel, aluminum radiator, 2 race seats, pulled out the AC assembly from under the dash, but it only weighed 38 lbs. Bumper assembly F&R weighed 186 lbs.

Wow, I didn't realize the bumpers were so heavy. I guess I should look into some fiberglass ones. what kind of weight difference could I get with glass hood and fenders?
