Description of Reference Points

REFERENCE POINTS - SYMMETRICAL
The symmetrical reference points are two corresponding points on the opposite sides of the centerline that are equal specifications in length, in width, and in height. Use the symmetrical reference points to make quick checks to determine the underbody structural damage.

REFERENCE POINTS - ASYMMETRICAL
When two corresponding reference points have different measurements they are asymmetrical. If you perform a quick cross check and the measurements are unequal, you must check the dimension charts to find out if the measuring points are symmetrical or asymmetrical. The underbody dimensions charts show specifications for both corresponding points when the measurements are equal.
