Factory part number 5086953aa: an o ring supplied by MOPAR.
Configuration note: Up to 11-10-03.
Flange nuts distribute clamping load without a washer, so a plain nut at the same torque will mark the component.
Confirm the number before you order, because a near match will bolt on and still be wrong. Send the VIN if the old marking has gone.
