Still in Qingdao, waiting for customs to release my stuff.
The footwell area had been repaired many times. Patches on patches, some welded, some braized and some pop rivetted.
The sill hadnt been welded at all behind the wing so I guess the sill was fitted without removing the wing at the time.
This meant that all the water that went behind the wing wheel arch area went into the inside of the sill. The result is more rust and the sand that had built up inside the sill over time.
With the sill removed the triangular foot area was revealed in its many layers. This was easy to repair with 1mm sheet steel and the sill and floor sections then added on.
