When you discombobulate a car to the point of loosing the dimensions from both sides at the same time, you need to do a three dimensional measuring of the car referring to the factory specifications and establish a datum line. If done one side at a time you can do comparisons. When dealing with front damage we use the nonadjustable sheet-metal to base our height measurement. IE. 1/4 panels. Once you damage both !/4 panels or bend the center section, 3-D measuring is required.
