C. High Roofs
Subsequent installation of a high roof
(Wheel bases 2.920 and 3.320 mm)
1. Preconditions
a)
The max. roof cut-outs may correspond only to those mentioned in section B3 of this construction guideline - the same
applies to the California. (see draft in section B3)
b)
The base vehicles may only be provided with max. one sliding door. In addition, it is not permitted to remove or weaken
any supporting parts - apart from the max. permitted roof cut-out. This applies also to the additional retrofitting of high rear
double-wing doors, a 2nd sliding door or changing to high sliding doors, etc.
2. Deviations of the Preconditions Valid for Pop-Up Tops
a)
The roof frame reinforcing set of Westfalia co. or an appropriate alternative are not required here. If, however, a second
base level is desired, these assembly sets can be helpful.
b)
The base vehicles may only be provided with max. one sliding door. In addition, it is not permitted to remove or weaken
any supporting parts - apart from the max. permitted roof cut-out. This applies also to the additional retrofitting of high rear
double-wing doors, a 2 nd sliding door or changing to high sliding doors, etc.
If a level passenger compartment/boot space floor is required, it is also permitted to use a water-tight chipboard. This
chipboard has then to screwed in or glued in flatly.
3. Design of the High Roof
a) Wheel base 2.920 mm
The high roof shell must consist of (min. thickness 4 mm) glass-fabric supported polyester.
b) Wheel base 3.320 mm
The high roof shell must consist of (min. thickness 4 mm) glass-fabric supported polyester and has to be reinforced with
an internally arranged bow in each of the areas of the B-, C- and D-pillars. (cross-section see draft 3.4, High roof
structure). The bows can either end directly in front of the car body or can be bonded to the car body. All bows are
provided with additional metal plates which are required for the supplementary mechanical connection of the high roof to
the car body. (see draft on page 18)
4. Mounting of a High Roof
a) Wheel base 2.920 mm
The high roof must be mounted sufficiently safe, i. e. the roof must be continuously bonded to the roof-frame exterior
plate. (see draft 3.4, High roof structure).
b) Wheel base 3.320 mm
In addition to the previously mentioned requirements, in the area of three countersunk bows, the roof must be connected
to the roof-frame exterior plate with the help of sheet-steel corner pieces. The sheet-steel corner pieces are to be
connected to the high-roof bows in the area (mentioned in section 3b) of the metal plates inside the bows. (see draft 3.4,
High roof structure)
