RRC rear tail lamp guard mounting hardware

I am looking for the upgraded aluminum mounting hardware for RRC rear tail lamp guards. This thing, the recessed screw within the threaded cylinder:



But I only need one of them. I have the other 3. In the meantime I have reinforced one of the crappy plastic stock pieces with epoxy, but I'd rather have the aluminum hardware in both mounting holes.

Good suggestion. I took your advice, and the seller said no, they won't sell the parts individually. But they offered to give me a deal on 4 of the aluminum mounting parts with no allen bolts or allen wrench. I guess I could order that and would have some spares. Not a high priority, but nice to have the option.
