I - DESIGN OF THE STRUCTURAL COMPONENT
This is a basic part; its only function is that of centre
floor side section.II - AREA TO BE CUT FOR PARTIAL
REPLACEMENT
This cutting line (4) affects the option of partially repla-
cing the centre floor side section.
III - ASSEMBLY METHOD FOR A PARTIAL
REPLACEMENT
Only the connections which are specific to the partial
replacement by cutting are indicated.
If there are other issues regarding access to mating fa-
ces, the various replacement options are described in
the basic instructions for structural bodywork repair
(see MR 400, 40A, General Information). WARNING
The information contained in the following descri-
bes the general repair procedure for all vehicles
having the same design for this part.
Before reading this general information, check that
there are no special notes associated with this vehi-
cle. These special notes will be specified if applica-
ble in other parts of this subsection dealing with the
par t.
