Devices for straightening portions of a vehicle, particularly the unibody and/or frame of a vehicle following a collision. A device comprising a clamp which is attachable to a pulling device which exerts a pulling force in a direction P. The clamp comprises jaws which open in the general direction of pulling force P to engage a flange or other portion of a vehicle extending away from the direction of the pulling force P. This aspect is particularly useful for repairing the wheelhouse of a vehicle. Another aspect is a clamp with two openings, preferably in a single set of jaws. One opening may, for example, open proximally, i.e., in the general direction of pulling force P, while the other opening may open in a direction away from pulling force P. Another aspect of the present invention comprises providing a plurality of clamps in a single pulling device wherein the clamps are connectable, via a chain, to a single pulling arm, and where the clamps are independently positionable relative to each other. For example, the clamps can be rotated, twisted, extended and/or retracted independently of each other for connection to portions of a vehicle all of which can then be pulled in a single pulling step. Another aspect comprises a device having a plurality of clamps which allow portions of a vehicle to be pulled sequentially during a single pulling operation.
