Abstract
Abstract A vehicle alignment gauge has a controlling member affixed to the rocker panel of a damaged vehicle to define a reference for measurements of frame, body and wheel damage relative to the central portion of the vehicle and a U-shaped rotatable measuring member rotatively coupled to the controlling member. The rotatable measuring member may be angularly adjusted so as to define an external datum plane from which dimensional measurements of the front, back, sides, upper and lower surfaces of the vehicle may be made.
