Grind down both sides of the knob at the end of the wiper motor arm until it’s flush with the arm.
Drill out the remaining material, starting with a small drill bit, and work your way up to a 3/8” bit – this
hole will be used for the linkage rod end.
Install one of the rod ends (FFR# 25724) with the supplied jam nut (FFR# 25725) onto the wiper motor
arm (½”,
9 /
16
” wrenches). You will have to trim some of the excess thread off of the rod end in order for it
to have sufficient clearance between it and the wiper motor mount plate.
Place the wiper motor in the mount plate (FFR# 25391) so the pins on the motor fit inside the holes in the
mount plate and the three threaded holes in the motor line up with the corresponding holes in the mount
plate.
