Up thru '68, the fender mounting hardware did it. There are enough of them 
that odds are that at least a few will make good contact. Then there's a short 
brown wire inside the headlight bucket that runs from the lamp socket to a 
screw to the bucket. That seems to work well, at least until things get old and 
rusty. 

I don't remember if there's a similar short brown wire at the rear. There 
probably is, or perhaps the 2 taillight mounting screws are expected to do 
the job. The taillights give much less trouble, because they see much less 
weather, just from being at the rear and having much better exits for water.

Starting in '69, VW added brown ground wires in the wiring harness to 
everything, so that very few things depended on a chassis ground after that. 
The starter and generator were the exceptions, although there was a ground 
wire from the generator to the voltage regulator, which was not expected to 
carry the generator output current.
