Wiper Transmission

I have rebuilt wiper pivots but it is a lot of work. Good ones are getting harder to come by.
I have also. My 67 model primary pivot post was so worn I had to buy another secondary pivot and transplant the shaft from it. Only good thing about the task is the sintered bronze bushings are generic (off the shelf) sizes/dimensions. Just thinking... it's been about 12 years. So long that I can't recall those 3 dimensions.
