There are two ways of determining vehicle measurements.
Tram Gage Method
A tram gage is used as a quick reference in order to determine vehicle damage. Use a tram gage set which includes a vertical pointer capable of reaching 914 mm (36 in).
Measurements of the engine compartment components are made from point to point with the vertical pointers equally set.
Other measurements are made on the horizontal plane, or datum line, parallel to the underbody with the vertical pointers set as specified for each point.
Dimensions that are measured to gage holes are measured to the center of the holes and flush to adjacent surface metal unless otherwise specified. Cross check diagonal dimensions in order to verify the dimensional accuracy of the vehicle underbody.
Three-Dimensional Method
In order to measure structural repair, use repair equipment capable of measuring multiple points of length, height, and width at the same time. Measure 2/3 of the vehicle body in order to obtain accurate comparisons to the vehicle structure.
Universal measuring systems combine the equipment and techniques used in order to make underbody and upperbody 3-Dimensional measurements. The universal system provides accurate measurements of length, width, and height measurements at the same time.
