wiper pivot repair?

Ok, there are bushings at each end. I thought from seeing and feeling the housing is worn. Not the harder shaft.
Those pivots are hard to find. Especially here

The shaft rotates only about 180 degrees. All the wear in bushing and shaft will be in half the surface. If the shaft is worn, a half turn will tighten it up. If all of the wear is in the bushing alone rotating the shaft wont make any difference.
If/when I'm only replacing pivot seals, I mark the housing before I remove it so I can put it back a half round from where it was.
