Model 205.0/1/2 

Model 253 

The following steps are shown on the left side of the vehicle and must be performed analogously on the right side in the event of damage.

1. Mark separating point on A-pillar paneling (5) and cut (areas A and B).

   Transfer separation points from vehicle.

2. Grind mating surfaces on A-pillar paneling (5) down to bare metal in crosshatched areas.

   Sand down spot weld flanges to bare metal on both sides.

   Model 205.0/1/2

   Grind mating surfaces down to bare metal on inside (area C).

3. Remove grinding dust.
4. Coat insides of spot weld flanges with zinc dust paint.
