I bought a 1968 camaro grille emblem and took the post studs off the back and added 3M to it. I chose the 68 grille emblem because it was close to flat but still had a curve to it to contour to the back of the trunk lid. You will have to flatten it a little, but it dont take much effort. Then you apply 3M and stick it on. I want to do the front grille to, but I plan to wait until I find the right style grille to change over. I dont really like the billet ones on the camaro. It is not nostalgic enough.
