Note: The back panel is joined to the side panel outer, rear floor side member and rear floor panel. It forms the base for the rear combination lamps and other parts and maintains the rigidity of the rear body. Pay particular attention to twists and parallelism and check mounting of related parts when welding.

This repair procedure gives you the option of using an installation procedure for either metal-inert gas (MIG) welding or adhesive bonding.
