A totally naked body in white '69 Barracuda weighs 461 lbs. That's 186 lbs at each forward spring hanger plus 89 lbs at the front end. I weighed it on an ordinary bathroom scale at these 3 points, deducting the weight of the yellow tubing of course. This figure includes paint, some road grime, and factory partial undercoating at just the rear wheels. (Also 1 wheel opening molding shown in the photo that was the very last piece to come off due to a stuck screw.)
I'd think a totally naked body in white '68 Dart should be close to the same.
I'm thinking weighting on two corners not four, one of the four corners will throw off the measurement, unless, your diagonal is off the block too.
