Never was one??? I was going to get that part eventually! Wonder why Ford thought it would only rain on the left side of the car?
Seems I recall reading somewhere that the driver side wiper pivot arm came thru the cowl close enough to the cowl vent located under the cowl that water during heavy rains could possibly splash inside the cowl vent and end up on the floorboard, so the engineers at Ford designed the rubber grommet to allow water to drip far enough away to prevent this from happening seems the passenger side pivot arm was far enough away from the cowl vent on that side to not need it
