An apparatus for locating a reference target on a partially assembled structure such as an automobile body frame. The apparatus has a base support structure for rigid mounting to a floor member, a transfer platform is attached to the base structure so that the transfer platform has freedom of movement in a first horizontal direction; a horizontal slide assembly is attached to the transfer platform so that it has freedom of movement in a horizontal direction perpendicular to the first horizontal direction; and a vertical slide assembly is attached to the horizontal slide assembly and is movable therewith in a vertical direction. An acutator and a clamp bar are utilized to immobilize the transfer platform, and an actuator and a clamp plate are utilized to immobilize both the horizontal and vertical slide assemblies. A plurality of work tools or tool receiving recesses are attached to the vertical slide assembly so that the tool and recess can move toward and away from the automobile body frame.
