3. Install B-pillar (1) with portal bracket, fit and fix in place.

   Use spacers.

4. B-pillar (1) (areas A and B).

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

5. Grind inert gas weld down flat (area B).
6. B-pillar (1) (areas C).
7. Solder surfaces on B-pillar (1) with body solder and smooth (area B).

   Alternatively to restorage of the surfaces with body solder, it is also possible to use a body basic spatula.

18. Install mounting rail (5), fit and fix in place.
19. Rivet mounting rail (5) Ø 6.5x12., 5 rivet (areas I).

    Clamping range 3.8 mm.

20. Mounting rail (5) (area J).

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

21. Solder surface on mounting rail (5) with body solder and smooth (area J).

    Alternatively to restorage of the surfaces with body solder, it is also possible to use a body basic spatula.
