I got it directly from GoMiniGo:
Nissan - GoMiniGo-Home of Innovative Products for your car
It was $85 for all and they will accept as return if you don't like it. Stillen wouldn't accept return for the mount, since they said it is considered used when you try to put on. That is what led me to these guys, as I didn't know if the kit would work on a 13. Go for the offset bracket if you want the same placement as I did. Fits closer inside the bumper opening better, and does not touch either top/bottom of the bumper. It has an additional extension spacer to add, if you want the plate to stick out more from the front.
