Factory cure for sucky early wipers?

[Clatter]

Soooo, The early-style pinch-bolt wiper shafts suck.
They strip.
The later splined style ones are way better.
My 67 has the early style ones, and they park on the left.
It seems that they kept parking on the left until 71,
When they started parking on the right.
Did the 68, 69, or 70 cars have the splined wiper shafts?
It would be sweet to get a wiper assembly, or arms and shafts,
And convert over.
Cause the early ones suck.
Or did i mention that already...?

The 68 and 69 used the same style of wiper shaft/arm attachment as the 67 and earlier did, but I think they got a larger diameter shaft also. The 70 was the first year for splined shafts, and the last year for parking on the left. They are all by their self. The 71 to 73 used splines as well, but they had shorter shafts (due to the fresh air box change, requiring a different wiper motor transmission), and parked on the right.
If you can find a 70 wiper motor assembly, get the 1 year only wiper arms to go with it. It's an almost direct swap (you have to open the holes up for the wiper shaft seals, as they are larger). I did thios to my 65 Notch, and I've been happy since.

The factory did have a cure for the early ones with the set screw, but you will never find the parts.
They re-designed the wiper arm, and instead of the set screw they had a pinch bolt.
One thing that was a killer on the set screw style, was people turning the wipers on, when the blades were frozen down, or the windshield was covered with snow in the winter.
Also, try and avoid using the high speed, unless you have to.
BTW, Bob, '69 is a 1 year only wiper arms and shafts. Prior to then, the shafts were 8mm diameter. '69, they changed them to 9mm.

I recently upgraded my Square this way:

Another upgrade I did was with the arms. I used a set of Bay bus arms and shortened them. This way I have a beefier arm with stronger springs to hold the wiper to the glass = better wipe.

Just another way to skin the ol' cat. . .

I will be using the 2nd version with the splined shaft. Will I have to use the 70 wiper arms? I understand that they are hard to find?

Another much simpler and less invasive cure for the pathetic early wipers is to make some bastardized wiper arms, like I did in http://www.thesamba.com/vw/forum/viewtopic.php?t=533211

The left arm is 331 mm long, the right 321.
Source of information: a period SWF catalogue I have.

Or....you can do it like many later cars did including the 411 and 412....and use equal length arms with one short and one long wiper blade. Ray

I have a fix for these I'll post soon if I remember. I'd sell it as a "kit" but anyone who ordered one would be pissed and give me bad feedback- it's that simple!
