Maybe I should set up a gofundme page 
I believe 84810-JK66E is the part number I need for a 2009 G37S sedan. In the description they say G35 G37, G37x w/ camera. No word of G37S but maybe the S is the same as the G37. Not sure why they would list the x separately, though. https://www.infinitipartsnet.com/oem-pa ... 84810jk66e
So would something like that work?

If it makes a difference, the camera and the button for the trunk are still there. It's just the molding that got ripped off.
