2. After removing the center pillar, remove the center pillar inner upper left on the body side.

1. When installing the side sill reinforcement outer rear, cut the center pillar reinforcement 80 mm (3.15 inches) downward from the installation hole of the rear door hinge because the center pillar reinforcement interferes with it. For the rear wheel house, remove the rear wheel house panel front lower outer and quarter panel extension inner because the quarter panel extension inner interferes with the rear wheel house panel front lower outer.
