This is a new 1955 1956 1957 Chevy car door hinge to the body side of the door jamb hex bolt kit. These are for all 2 door cars and the front doors of all 4 door models. These are the hex headed bolts that are way deep inside the hinges when they are bolted to the body side of the door jamb. If you open the door and look down inside the door hinge pocket, you will see these hex bolts. The yellow arrows in the third picture show where these bolts are located, down inside the hinge pocket. One kit needed per car. We also carry the Phillips head screws that are mounted on the surface of the door jamb and the door hinge to door bolts in our store. Sku # 11680
