Factory part number 89002272: an element supplied by GM. It is catalogued under Accessories & Mounts > Inserts & Elements.
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. 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.
The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Handed to the carrier within one to two business days from our US warehouse, free over $59.
