Outer Front Pillar, Center Pillar
and Quarter Panel Sectioning
CAUTION: When performing service on or near the Supplemental
Inflatable Restraint (SIR) components or the SIR wiring, the SIR system
must be disabled. Failure to follow the correct procedure could cause air
bag deployment, personal injury or unnecessary SIR system repairs.
The full body side outer panel comes as a one-piece assembly and can be
replaced at factory seams after removal of glass and roof. Any one of these
procedures can be performed separately, or in any combination, dependent
upon the extent of damage to the vehicle. Sectioning must take place in
specified areas only (Fig. 1-1). Remove front glass when sectioning front pillar
and rear glass for rear pillar repair.
IMPORTANT: When replacing panels that involve servicing stationary
glass, refer to GM Service Bulletin 43-10-48 before performing any
priming or refinishing.

Sectioning
Removal Procedure
IMPORTANT: Sectioning should be performed
only in the recommended areas. Failure to do
so may compromise the structural integrity of
the vehicle.
1. Visually inspect and restore as much of the
damage as possible to factory specifications.
2. Remove the following:
• Fender
• Windshield
• Door
• Hinge pillar blocks
3. Determine sectioning locations. Section in
approved areas only (see Fig.␣ 1-1).
4. Mark locations and cut part through outer
panel only.
5. Locate factory welds and drill out, noting
number and locations of welds (Fig.␣ 1-2).
6. Locate and drill out spot welds on weather
strip retainer as necessary. It is not necessary
to remove complete retainer.
7. Remove outer panel.
8. Note placement and number of foam baffles
for new installation. If baffles are damaged,
replacement service parts are available.
IMPORTANT: Hinge pillar blocks must be
replaced if damaged.
9. Clean adhesive and sealer from hydroformed
reinforcement tube as necessary. Note
location for reinstallation.
Service Part Preparation
1. Cut service part in corresponding locations to
fit original cut lines. Leave a gap of one-and-
one half times the metal thickness of
sectioning joint.
2. Create 100␣ mm (4␣ in) backing plate on rocker
panel from unused portion of service part
(Fig.␣ 1-3).
3. In windshield pillar area, use the hydroformed
inner rail for backing plate.
4. Drill 8␣ mm (5/16␣ in) plug weld holes in service
part according to original locations as noted.
Drill plug weld holes spaced 40␣ mm (1-5/8␣ in)
apart along backing plate location 25␣ mm
(1␣ in) from joint edge.

25␣ mm (1␣ in) welds along the seam with
25␣ mm (1␣ in) gaps between, then go back and
complete the stitch weld to ensure structural
integrity of the vehicle.
8. Install insulating foam as necessary in areas
noted from original baffle locations.
IMPORTANT: Prior to refinishing, refer to
the publication GM4901M-D-2000 “GM
Approved Refinish Materials” for

Outer Center Pillar
Sectioning
Removal Procedure
IMPORTANT: Sectioning should be performed
only in the recommended areas. Failure to do so
may compromise the structural integrity of the
vehicle.
1. Locate an approved sectioning area in the
center pillar (Fig.␣ 1-5).
2. Mark and scribe a line. This is the cut location.
3. Cut Center Pillar at cut line. Use caution not to
cut inner reinforcement.
4. Create cut lines on rocker within approved
sectioning locations. Cut the rocker vertically
along cut lines.
5. Drill out factory welds. Note number and
location of welds.
6. Remove the damaged part.
7. Note placement and number of foam baffles
for new installation. If baffles are damaged,
replacement service parts are available.
IMPORTANT: Hinge pillar blocks must be
replaced if damaged.
Preparation Of Service Part
1. On the service part, at center pillar mark a
horizontal line in corresponding locations
to original sectioning cut. Leave a gap of one-
and-one-half times the thickness of the metal
at the sectioning joint (Fig. 1-6).
2. Mark vertical cut lines in rocker areas to
correspond with original section lines. Leave a
gap of one-and-one-half times the metal
thickness (see Fig. 1-3).
3. Cut the outer doorframe opening service part
along these three section lines.
4. Cut two 100␣ mm (4␣ in) pieces from the unused
portion of the service part for backing plates
in rocker.
5. Cut one 50␣ mm (2␣ in) backing plate for pillar
(Fig. 1-6). Remove the flange on each side of
the backing plates so that they will fit behind
the sectioning joint.
6. Drill 8␣ mm (5/16␣ in) plug weld holes in service
part according to original locations, as noted.
Drill plug weld holes spaced 40␣ mm (1-5/8␣ in)
apart along backing plate locations. Space
these holes 25␣ mm (1␣ in) from the joint edge
on the rocker panels and 13␣ mm (1/2␣ in) from
the joint edge on the pillar.

CAUTION: When performing service on or near the SIR
components or the SIR wiring, the SIR system must be disabled.
Failure to follow the correct procedure could cause air bag
deployment, personal injury or unnecessary SIR system repairs.
The full bodyside inner panel comes as a one piece assembly and can

Inner Front Pillar
Sectioning
Removal Procedure
IMPORTANT: Sectioning should be performed
only in the recommended areas. Failure to do so
may compromise the structural integrity of the
vehicle.
1. Visually inspect and restore as much of the
damage as possible to factory specifications.
2. Remove outer panel according to specified
directions in Outer Panel Removal procedure.
3. Remove all necessary components to allow
access to repair area.
4. Locate and mark a horizontal line 50␣ mm
(2␣ in) down from the raised, square portion of
the hinge pillar (Fig. 1-12). This will be your
cut location (1).
5. At rocker panel, locate and mark a vertical cut
line in the approved sectioning location
(Fig.␣ 1-12).
6. Cut at the two marked locations. Use caution
to cut through one layer of metal only.
7. Locate and drill out factory welds noting the
number and location of welds.
8. Remove damaged section from vehicle.
Preparation of Service Part
1. On hinge pillar, scribe a cut line 25␣ mm (1␣ in)
below the raised, square portion of the hinge
pillar. This will create a 25␣ mm (1␣ in) overlap
on the service part.
2. Notch the panel on the door weather-strip
flange (1) to prevent excessive metal thickness
in this area (Fig. 1-13).
3. In rocker area, locate and mark a cut line in
the recommended sectioning area. Allow for a
50␣ mm (2␣ in) overlap to the vehicle sectioning
areas (Fig. 1-13).
4. Cut along marked sectioning lines to create
service part.
5. Notch upper and lower edges of service part
(2) to prevent excessive metal thickness in this
area (Fig. 1-13).
6. Drill plug weld holes spaced 40␣ mm (1-5/8␣ in)
apart along overlap flanges. Place holes
25␣ mm (1␣ in) from edge on rocker panel and
13␣ mm (1/2␣ in) from edge on hinge pillar.
