A system for measuring the orientation angle of automotive collision avoidance sensors. An adaptive spacer is supported to conformably interengage the collision avoidance sensor module of a vehicle being repaired. The adaptive spacer extends outwardly from the sensor module and the orientation angle of the sensor module is transposed by the adaptive spacer to form an angular guideline on an underlying calibration board, mat or other surface. The angle between the angular guideline and a base guideline parallel to the center line of the vehicle and the angular guideline is measured to provide the orientation angle of the vehicle's sensor module.
