Apparatus for pivotally interconnecting a force applying member to an apparatus for repairing and straightening is disclosed in its preferred form for use in repairing and straightening the body and frame of a vehicle. The disclosed apparatus includes a small cylindrical pivot member mounted in a first stationary position located adjacent the front of an apparatus for repairing and straightening and second and third small cylindrical pivot members mounted to a tram movable within the apparatus for repairing and straightening. A force applying member in the form of an elongatable pull tower is shown together with a connector arm which extends from the pull tower to a point adjacent to the pivot member. A clamp member and a ring sleeve type bearing are provided according to the present invention to pivotally mount the connector arm to one of the pivot members. Thus, under the teachings of the present invention, the counterforces applied to the connector arm by the pull tower can be conveyed to the pivot member from any direction. Further provided according to the present invention are positioning and leveling members including a thrust plate and adjustment screws which abut with the thrust plate. A nylon type bearing is also provided between the thrust plate and the clamp member to reduce the amount of friction between the thrust plate and the clamp member when the connector arm is pivoted about pivot member.
