OK, Mine came.
How is everyone attaching them? By that, I mean what means are you using to hold them onto the rear grille?
The two posts appear to be designed to accept a body style pinch nut but the diameter is pretty large for the first 3/4" preventing a pinch nut from bottoming out against the backside of the grille.
I also received mine yesterday and today did the install: I tapped the upper lower poles to accept a 10MM bolt.....I used aluminum bolts as the cast poles are fragile. I carefully cut some felt strips to prevent scratching on the badge backside. To provide a firm fix black washers were used so the bolts would not press on the mesh opening. After hand tightning the bolts (through the license Plate opening) used a 10mm box wrench to give them a gentle nudge. I would not over tighten....
