The early wiper arms were just attached to the shafts with set 
screws, and that attachment was always troublesome. For '68-9 the 
shaft was 8 mm, but earlier shafts were only 6 mm. VW actually had a 
recall that replaced the set screw wiper arms with a pinch clamp 
style. Those worked well. You will have to look at your arms to see 
which style you have.

If you have the pinch clamp style, you just need to tighten the pinch 
bolt. If you still have the original set screw version, you will 
probably need to file a small flat on the shaft for the set screw to 
bear against. This is difficult, because the flat has to be in 
exactly the right place, or the wiper won't face in the correct 
direction. Work slowly and check your work often.

You could also be on the lookout for a pair of the 6 mm (I think) 
replacement pinch clamp versions. Those would be your very best 
option, as they worked very well, but they will be hard, or 
impossible, to find.
