72 Demon Ride Height Question.

There is no "one" measurement. The road height is the difference between two measurements. Measurement "A" is the one from the bottom of the front torsion bar anchor to the ground and measurement "B" is the from the bottom of the lower ball joint to ground. The difference on your car should be 1 5/8" (at least the Duster is and I'm assuming the Demon is the same) These measurements have to be taken with the car on level ground, with a full tank, tire pressure correct, no people inside, and all the extra junk out of the trunk. Make sure both sides are within 1/8" of each other.
