The insert here is the GM part, numbered 85048232. It is catalogued under Accessories & Mounts > Inserts & Elements.
The photographs on a listing show the actual stock item, so compare the mounting points and the connector or fitting rather than the overall shape.
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. Handed to the carrier within one to two business days from our US warehouse, free over $59.
