John, I researched this because we are selling 5-cylinder conversion kits for
Caravelles here in the US (they call  them Vanagons here).  I found that
there were no manuals available to the average man over in SA and that the
dealer shop manuals were super pricey (like $300 just for the engine manual
and then another $300 for the body manual).  I would say your best bet is to
get a Bentley Manual from over here as this will help give you a better idea
of what is going on with your van body etc, but there are so many differences
in your van than what we have here:
15" rims, bigger vented front disc, bigger rear drums, suspension is
different, not to mention the motor (over here we had 4-cylinder aircooled
boxer engines, then diesel in line 4 cylinders, then the waterboxer a
watercooled 4-cylinder boxer engine and that was it).
