Abstract: An assembly of components and a method of using such components for straighening and repairing vehicle bodies, frames or for bending various metal components in an efficient manner. The present invention includes the use of hydraulically actuated rams to provide a force to straighten or bend metal components and a chain or similar structure to transfer the force produced by the hydraulic ram to the metal component to be straightened or bent. Unique base plates are provided for supporting one end of the hydraulic ram from a vehicle runway, platform or other stationary surface. A unique socket and stop assembly is provided for supporting the hydraulic ram from a transverse beam and also to form a stop for precluding movement of the transverse beam.
