7. B-pillar reinforcement (2) (areas B).
8. Remove side portal frame and portal straightener.
9. B-pillar reinforcement (2) (areas C).

   Inert gas weld in intervals and allow welding area to cool down in between. Reduces heat distortion.

10. Face grind inert gas welds on B Pillar reinforcement (2) (areas C).

    Grind down flat on contact surfaces on B-pillar paneling and beaded area only.

11. Clean weld joints no longer accessible after installing A-pillar reinforcement and coat with zinc dust paint.

25. Install B-pillar paneling (1) and longitudinal member paneling (3) and fix in place.
26. Rivet B-pillar trim (1) and longitudinal member paneling (3) with rivets ø 6.4x12 (area X).
27. B-pillar paneling (1) and longitudinal member paneling (3) (areas Y).
28. B-pillar paneling (1) and longitudinal member paneling (3) (areas Z).

    Inert gas weld in intervals and allow welding area to cool down in between. Reduces heat distortion.

29. Sand inert gas welds down flat (areas Z).
30. Solder surfaces on B-pillar paneling (1) and longitudinal member paneling (3) with body solder and smooth (areas Z).

    A basic body filler can also be used as an alternative to the restoration of the surfaces with body solder.
