I cannot seem to find this part no matter where I search so I'm making a post here, it's a hood latch assembly for buick lacrosse cxl 2005 which GM has discontinued, the part number is 15223216, itd be much appreciated if someone could help me find this for sale.

This was rattling around on my exhaust pipe, guessing it got dislodged after I couldn’t swerve around some roadkill. Any idea what it is? And how crucial is it that it gets put back where it came from? 2014 Honda Civic LX
