2. Remove all related panels and components.
3. Cut the rear floor along the rearward edge of the crossbar. Be careful not to cut the crossbar or rear rails.
4. Remove the damaged section of the rear floor.
5. Locate, mark and drill out all factory welds rearward of the crossbar connecting the rear rails.

1. Position the new floor section on top of the original floor.
2. Check the fit according to body specifications and plug weld accordingly.
3. Clean and prepare welded surfaces.
