Battery HOLDDOWN: Description
WARNING: This page is about a different car, the 2004 Dodge Pickup and 2004 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The battery hold down hardware includes a bolt and a molded plastic hold down bracket which meshes with the battery tray when properly installed. The battery tray and hold down hardware combine to form a very stable and secure battery hold down assembly.
