Factory part number 68134030aa: an o ring supplied by MOPAR. It is catalogued under Nuts & Washers > Rings & Retainers.
Genuine parts are made to the drawing the vehicle was built from, so dimensions and materials match the part being removed rather than being close to it.
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. In stock and sent from the US in one to two business days, free delivery over $59.
