Since many of our Mustangs have seen better days the years show up most often in a change of ride height.  Most of use realize that Mustangs have a tendency of sag in the rear after many years or use.  But how to you determine if your car sits too high or too low now that the restoration is complete.  Again a Technical Service Bulletin has an answer. 
In an April 1966, Ford published a bulletin which dealt with the subject of ride height.  It included the steps necessary to measure the ride height correctly and the correct height.
 
1. Place car on level ground
2. Push down on the front bumper by at least 1 inch. This will settle the suspension.
3. Measurements are made at the center of the front and rear wheel wells, directly over the center of the wheel.
4. Then lift up on the bumper, by 1", let settle and repeat measuring process.
5. Average both measurements.
6. Repeat process on rear of car.                
 
Note: Measure the front completely before doing the rear
