Windshield Wiper Pivot Bushings

Guys, please explain the windshield wiper pivot bushings. My 70 Coronet has these little plastic plates with bushings that are split on top and no cap. All I can find to replace them is this.



I don't see how it works, especially with the little tab on it. They seem too small for the shaft. What's the deal?

2 or 3 speed?

Is there a difference in the bushings used between the 2 and 3 speed systems?

My 68 Barracuda has 3 speed wipers and uses the black square based bushing pictured above.

That's the beast. Mine is a three speed. Why the heck doesn't anyone sell them? all the ads and information say that it's for all 1966-1976 a/b/c body and 70-74 E body. That's lame...
