ABSTRACT:
Acccessories are disclosed, in their preferred forms, for use in conjunction with an apparatus for repairing and straightening vehicles having a support surface, for supporting vehicles thereon, including an array of regularly shaped apertures which extend vertically therethrough. A unibody clamp is disclosed including adjustable jaws for removably gripping the pinch weld of a unibody frame. Abutment wings are further provided on the clamp for abutting with a stop member which accepts, substantially in line, the counterforce from the clamp. A first connector member is further provided on the clamp for attaching a chain held in an elevated position by an elevated chain apparatus. First connector member further allows the use of a down pull member including a chain directed to the clamp by a rotatably mounted pulley. A second connector member is further provided on the clamp allowing the exertion of a force perpendicular to the pinch weld of the unibody frame. The stop member, elevated chain apparatus, and down pull member are removably attached to the support surface by an attachment member which extends into a selected support surface aperture and allows self-alignment thereof in the support surface.
