There are two things to consider. First, the front ride height is adjustable by turning the bolts on the torsion bar anchors. Second the rear ride height is adjustable by modifying the springs (reaching, adding leaves, etc.).
The proper way to measure ride height is given in the service manual which is measuring form the ground to certain points on the car undercarriage.
Generally as the car ages, the rear leaf springs tend to sag so it would not be uncommon for the rear to be lower than it was when new.
