Hey Justin,
I spent about ten minutes at the hardware store dinking with bits and pieces, nuts, bolts and washers and bought some brass metal stock. I cut the stock to just under the badge's width, drilled out the holes and then, was home free...well, I made a second trip to the hardware store to get some longer little brass carriage bolts or stove bolts or whatever they were called... I also put a dab of silly-cone on the back of each badge and afixed a small, thin rubber washer so there wouldn't be any scratchin' or wigglin' shinnanigans between the badge and the grille... Then I reinstalled the grille into the decklid.
P.
