9. Install longitudinal member paneling (1) and fix in place.
10. Rivet longitudinal member paneling (1) with rivets with a diameter of 6.4x12 (area C).
11. Rivet longitudinal member paneling (1) with countersunk head blind rivet with a diameter of 6.4x14.0 (area D).
12. Rivet longitudinal member paneling (1) with countersunk head blind rivet with a diameter of 6.4x15.5 (area E).
13. Longitudinal member paneling (1) (areas F).
14. Longitudinal member paneling (1) (areas G).

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

15. Grind inert gas weld joints down flat (areas G).
16. Solder surfaces on side longitudinal member panel (1) in area of inert gas welds with body solder and smooth.

    As an alternative to restoring the surfaces with a body solder, it is also possible to use a basic body filler.
