The element here is the GM part, numbered 19112881. 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. The number stamped on the old part is the only reliable identifier, since two parts can look identical and differ by a millimetre or by rotation direction.
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.
