Abstract: A measuring bridge coupled to a vehicle by means of a plurality of vertical elements attached to datum points on undamaged portions of the vehicle to properly orient it to the vehicle. In addition, vertical measuring elements attached to datum points in damaged portions of a vehicle are supported on the bridge for movement in two perpendicular directions and a plane parallel to the vehicle and extend along their length to follow and monitor the reforming of the vehicle during the application of force. The measuring bridge is supported by a plurality of air pressure cylinders to maintain proper orientation of the bridge with respect to the vehicle.
