After removing my rear center light, I noticed a couple of these plastic clips had broken. Not sure what the difference between FD02-50-792 and FD03-50-792 is, but according to the diagram I need one of each. They clip into the back side of the rear center light.

No longer available from Mazda or anywhere I can find online, anybody have extra of these laying around?

I'm going to take a look at the car again tomorrow and see what fasteners would go into these, because there are already 6 studs on the same plane on the center light that attach to a bracket on the body with nuts.
