The clamp style, with the pinch bolt, are good. The set screw style are hard 
to keep working. If you can get a second pinch bolt style, that would be easy 
and keep the car "original." It will be hard to find the correct arm.

I don't think there's anything special you have to do to swap in a '70 setup, 
but it's a lot more work, and probably a lot more expensive.

'68-9 cars all came with the set screw style, but VW did a recall to replace 
them with the pinch bolt style. As with all non-safely recalls, not every car got 

For '68-9s:

Left arm: 311 955 407 B

Right arm: 311 955 408

Earlier cars had the same problem, except that the stub the arm was 
supposed to grab onto was even smaller (6 mm?) For those cars, the pinch 
bolt arms are the same: 311 955 407 A.

When I got my '69 the wiper arms were loose on the shafts, because the 
shafts were so buggered up that the arms could not slide all the way onto 
them. I managed to file off the high points so the arms could fit. They have 
worked fine, but I'm not sure if I have the L & R on correctly. I may even 
have two lefts or two rights. Too bad they're not marked.
