them with the cut area of center pillar reinforcement in the

mm (3.94 inches) below from the cut area to create a cover, 
and then cut the rear door hinge reinforcement 50 mm (1.97 
inches) below from the cut area.

4. Weld the rear door hinge reinforcement then weld the cover 

of the center pillar reinforcement.

5. When installing the new center outer pillar, machine the 

body loose panel cushion (MR535301 or MR435765) for 
replacement as shown and apply it to the body side because 
the sound dampening foam material cannot be filled into the 
front pillar.
