This is analog bathroom scale weights of parts of a '69 A-body with front drums in lbs., which should be similar to E-body. All parts are totally bare and without fasteners unless noted.

460 totally naked body shell w paint, w/o undercoating or interior caulking.
32 R or L door, each.
39 trunk.

Total of all above is 1,062 lbs w/o wheel/tire assemblies, steering column/steering wheel parts, any hinges, or interior door parts.

Since the weight on each of the 4 wheels is transmitted through a spring or torsion bar, any extremely minor change to any of the spring heights will change the weight under all of the wheels. This means jacking up each wheel and putting a scale under one wheel at a time will yield only false readings. To weigh a car accurately you would need a scale under each wheel simultaneously. Bathroom scales are mostly 300-350 lbs max, so 2 of these would work under front wheels of a stripped down car, but the weight of the rear wheels might be over max capacity of these scales. You could put 2 bathroom scales under each rear wheel with a 2x4 bridge between them. Buy as many as you need and return them after you're finished.
