摘要： An apparatus and method for straightening damaged unibody-type vehicles whereby a lightweight rectangular frame is attached at its four corners to the longitudinal pinch weld which runs along both sides of the vehicle body. The frame members are rigidly connected to each other but telescopingly adjustable in length to accommodate different size vehicles and have pulling attachment points at the corners of the frame allowing pulling or pushing in any direction.
