A dual probing tip system uses a slot and rail system to provide variable spacing and lateral and axial compliance of the probing tips mounted on first and second support members. A movable base member is secured on a frame with the base member having a rack of linear teeth and a pair of rails angled toward the front. First and second intermediate carriers each have a slot that engages one of the angled rails. Each of the carriers has stanchions that receive a thumb wheel pinion gear mounted on a shaft. The pinion gear mates with the teeth on the base member for movement of the carriers. Each support member has an axial slot that mated with an axial slot on each one of the carriers. Each support member has a compression spring which allows axial compliance of the support members.
