Body and platform form a self-supporting unit on the Kombi/panel van. Structural parts of this selfsupporting unit should not be removed without replacement. Partition walls do not have a structural function. Modifications other than complete removal are permissible. Only weld body parts for installation or conversion if a bonded connection is not possible.

• Sidewall apertures
  If sections are cut through for the apertures (windows, doors, flaps, ventilation outlets/inlets, etc.), the apertures must be reinforced with a surrounding frame and welded to the sections that have been cut through.
• Roof height increase (synthetic roof)
  see item 3.6 Roof design

Seat securing points 

Seat securing points cannot be retrofitted in the panel van, this is because the securing points lie in the longitudinal and/or cross member.
