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
