Wiper Linkage

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.
