This is a f panel from GM, factory part number 84774819. It is catalogued under Covers & Caps > Panels & Plates.
Corrosion at a mounting face is worth cleaning back before fitting anything new, because a part that sits on scale will work loose. On panel and plate parts, check whether the original is held by clips, screws or both. The fasteners are often sold separately and are often what actually broke.
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. Leaves our US warehouse in one to two business days, and shipping is free over $59.
