Wiper Linkage

[71droptop]

I have gotten many Good leads from the site as far as who rebuilds wiper motors.
Having a little trouble getting a handle on the whole linkage issue. Im converting from 2 spd. switch and motor to Ralley 3 spd and motor.
Im told if I use the existing linkage under the cowl the wipers wont park.
So Ive been on a search for link 2822 289 and 2822 293.
Any help Really appreciated.

The linkage is different between a 2 and 3 speed. I believe the wiper pivots that mount the actual wiper blades are the same.
The 3 speed linkage has two variations 70 -71 and 72 -74.
The cranks on the wiper motor are different for each style. From memory the little shaft that comes out from the wiper motor are different sizes so you need the wiper motor first to get the correct crank.
From there obtain the correct linkage to suit the motor/crank.
