The next steps are shown on the left side of the vehicle in model 177.0. In case of damage on the right side of the vehicle, these steps must be performed analogously.

The higher-level service document as well as the safety information in the service document must be observed.

1. Install, fit and fix in place A-pillar paneling (1).
2. Drill rivet holes in A-pillar paneling (1) with 6.7 mm diameter (areas A₁ , A₂ ).
3. Drill A-pillar paneling (1) with 6.0 mm diameter through one panel thickness for plug welding (area A₃ ).
4. Remove A-pillar paneling (1).
5. Deburr rivet holes in A-pillar paneling (1) and at body on both sides.
6. Remove drilling chips.
7. Coat insides of the riveted joints with zinc dust paint (areas A₁ , A₂ ).

11. Install and fix in place A-pillar paneling (1).
12. Rivet A-pillar paneling (1) with rivets Ø 6.4x12 (areas E₁ , E₂ ).
13. A-pillar paneling (1) (areas D₁ , D₂ and D₄ ).
14. A-pillar paneling (1) (areas F, G).

    

    Perform inert gas welding at intervals and allow to cool down in between. This reduces heat distortion.

15. A-pillar paneling (1) (area D₃ ).
16. Grind inert gas welds flat (areas F, G).
17. Solder surfaces of A-pillar paneling (1) with body solder and smoothen (areas F, G).

    

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