Info and help Re: wiper transmission

RedFish said

I've never had both 2 speed and 3 speed 67 wiper linkage on the bench at the same time so I cant say for sure if there is any other difference besides the one bushing at pitman arm. Steve aka 4spragtop may have found that answer during his build.
Good luck

Thanks Ben, I don't think I had all the linkages out at the same time to compare. I think it was one linkage piece at a time.

BUT in my mind the linkages shouldn't be any different from 2 to 3spd?? Im thinking that the only differences from 2 spd VS 3 spd would be in the switch and motor.
Of course there are the differences in years as well.

Ed post pics and more info if you can. What kind of bushings does the linkage have?
