DESIGN OF THE STRUCTURAL COMPONENT
This is a basic part, its only function is that of the winds-
creen pillar lining.
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). Note:
The information contained in the following descri-
bes the general repair procedure for all vehicles
having the same design for this part.
Before reading the following general information,
make sure that there are no special notes associa-
ted with the vehicle. These special notes are speci-
fied if necessary in other par ts of the sub-section
dealing with the component.
Note:
For a detailed description of a particular connec-
tion, see MR 400.

WARNING
If the spot welds cannot be made as they were ori-
ginally using an electrical spot welding machine,
they should be replaced with plug welds after holes
have been drilled in the first panel.

III - POSITIONING OF LOCAL ELECTRICAL
EARTHSIMPORTANT
For welded connections in three thicknesses, the
spot welds on the part replaced should be made in
the same place as for the original joint to retain its
mechanical proper ties.

IMPORTANT
To avoid damaging the vehicle's electric and elec-
tronic components, the battery and the earths of
any wiring harness near the weld area must be dis-
connected.
The earth of the welding machine must be placed
as close as possible to the weld area.

DESIGN OF THE STRUCTURAL COMPONENT
The two parts must be welded at the joint (1) and butt
welded by continuous EGW welding.
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).
The body side is achieved by welding the rear wing and
the body side front section.Note:
The information contained in the following descri-
bes the general repair procedure for all vehicles
having the same design for this part.
Before reading the following general information,
make sure that there are no special notes associa-
ted with the vehicle. These special notes are speci-
fied if necessary in other par ts of the sub-section
dealing with the component.

To carry out a replacement of this part, order the A-
pillar (1) with the rear wing panel (2) .
The parts supplied are long enough to cover the parts
to be replaced.
