weighed my 72 dart

WOW! Thats real light. My 70 Dart was 3330 pounds with a full tank of gas and a full size rally spare tire in the trunk. Sence then I have got it down to 3250 pounds.

Glass bumpers should shave about 30 pounds. Sence you are going glass you could just run the inner bumper mounts on the front for a loss of another 3 pounds or so each and drill holes in the inside mounts and the rear ones two.

Don't know about the hood. Depends on if you are going bolt on or lift off. But I would think around 30/40 pounds or so.
