An apparatus for measuring the dimensions of an articulated connector for reconditioning while it is still mounted to the end structure of a rail car is disclosed. The connector is measured to find areas and amounts of wear on portions of the connector. The measurements are taken relative to a reference portion of the connector. A pivot gauge apparatus can be used to determine if a male casting meets industry standards. The pivot gauge includes a fixable base for interaction with the casting and a pivotably mounted arm with measurement portions.
