The Camaro emblem is a tough call. When judging, we take off for the repro emblems as the script is too "fat", slightly thicker and flatter on top than originals. If you buy the GMs today, there is a small imperfection on the "B" in the word "BY." So you're damned if you do and damned if you don't. If I had to choose between these two, I would probably use the repros. Some of the current GMs also have a lot of flashing.
