Removal Procedure
Important: The striker plate is mounted in a cage that allows some degree of adjustment
independent of the outer panels position. Use body dimensions to ensure that
     the striker mounting location falls within the plates range of adjustment.
- Remove all related panels and components.
 
- Visually inspect and restore as much of the damage as possible.
 
- Remove sealers and anti-corrosion materials as necessary.
 
Important: Sectioning should be performed only in the recommended areas.
- Cut the reinforcement
(3) panel 255 mm (10 in) from the lower edge of the door opening.
 
Important: When sectioning both the inner (3) and the outer panels (2) this should
result in a 55 mm (2 3/16 in) offset in  the sectioning
   joints.
- Remove the damaged center pillar reinforcement (5).
 
Installation Procedure
- On the service part (5),
mark a horizontal line to leave a gap of 1½ times the thickness   
 of the metal (6)at  the sectioning joint.
 
- Cut the service reinforcement panel along this line.
 
- Cut a 50 mm (2 in) piece from the unused portion
of the service   part for a backing plate (5).
 
- Remove the flange on each side of the backing plate (4) so that
it will fit behind the sectioning   joint.
 
- Drill 8 mm (5/16 in) holes for plug welding in the
service part in the location noted from the original  panel.
 
- Drill holes for plug welding along the sectioning cuts on both
the service part and the original panel.
 
- Locate these holes approximately 13 mm (1/2 in)
from the edge of the sectioning cuts.
 
- Prepare the mating surfaces and position the backing plates with
 25 mm (1 in)  of the backing plate exposed, then plug weld.
Position       the service part  to overlap the exposed 25 mm (1 in)
gaps    between.
 
- Go back and complete the stitch weld. This will create solid joint
 with minimal heat distortion.
 
- Clean and prepare welded surfaces.
 
- Prime with 2-part catalyzed primer.
 
- Apply sealers and anti-corrosion materials as necessary.
 
Important: Prior to refinishing, refer to GM4901MD-99 Refinish Manual for recommended
products. Do not combine paint systems. Refer to paint manufacturers recommendations.
- Install all related panels and components.
