Part number for baggage door hinge

[bcrvman]

Where can I get the part number for just the hinge of a baggage door. These are the waterproof hinges that from the end look like a C inside a C.
I need a web based approach as my phone only works in Canada.
The hinge is 46 3/8 long. It goes on the door side baggage door of a 2018 3811MS. Picture of the door half of the hinge attached. The other end is the bad part, this is what they look like when not damaged.
