Remove related panels and components,
including rear compartment panel. Also
remove the fuel tank from the damaged side
of the vehicle.
Notice: Save any and all brackets,
mounting studs, and accessories for re-use
as necessary.

The outer lock pillar extension panel must be
removed to access the rail. Apply a piece of
25mm (1 inch) tape along the lock pillar
(Fig.␣ 3.27), and cut to create a weld flange for
installing the new extension panel (Fig.␣ 3.28).
Caution: Sound deadener foam in the lock
pillar can be a fire hazard. Avoid welding
to the lock striker pillar.

Using a die grinder, cut along the edge of
tape line. Cut stitch welds along the rail and
drill out the resistance welds along the tunnel
brace. Remove lock pillar extension panel.

The upper extension panel for the fuel tank
must be loosened and pried up for access to
the rest of the rail for sectioning (Fig.␣ 3.29).

recommended areas), and cut the damaged
rail accordingly. (S
