Gap:

I am actually thinking of fabricate my own out of flexible plastic sheet rather than pay $90/ea for those 4 pieces ($400+) but I will use a rivet gun to mount it on my bumper. I haven't gotten that part yet, but I assume it's like a Rivet gun. I will paint the rivets black if the OEM Rivets don't come colored black. I think I can get away with hiding it because I have a Magnetic Black 370z.

Let me know what you end up doing. Cheers!
