Caution: Refer to Approved Equipment for Collision Repair Caution in the Preface section.

Important: The damaged rear floor is cut along the rearward edge of the rear crossbar (1), and the service part is cut to that the new floor section extends to the forward edge of the rear crossbar (2). This allows the two sections to overlap where the crossbar is attached (2). The service part is supplied as a rear floor assembly (3) which requires cutting to fit. The cut will be about 845 mm (33¼ in) from the rear edge of the forward panel.

1. Disable the SIR system. Refer to SIR Disabling and Enabling in SIR.
2. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
3. Remove all related panels and components.
4. Repair as much of the damage as possible to factory specifications. Refer to Dimensions - Body .

Caution: Refer to Foam Sound Deadeners Caution in the Preface section.
