Using one OEM tow loop front and rear I use a fixed lenght chain at the rear. Pin and clevis at the OEM rear tow loop and chain hook around 2 x 2 x 1/4 trailer angle iron open trailer. At the front I use a pin and clevis at the OEM tow loop with a logers over center lever with a chain hook around a 2 x 2 x 1/4 angle iron. By tightening down with the tow loops the suspension is taken out of the equation which I believe is a good thing. Less shock and spring movement. The chains have NEVER been found loose and the car has never moved in any direction while on the trailer.:cool:
