WOW That sucks about the fail damage, glad it was fixable ! When I replaced my carbon fiber black gloss hood insert with an exposed carbo finger hood insert and I had to add the ZL1 hood insert emblem's on each side. I measured the proximity of the originals, and transferred that using tape for reference. I made sure they were at the correct angle and PRESETO! I got them wrong slightly. But, no one but I will ever notice! My point being, someone here can give you the approximate locations and then you can add them where they generally go. Just make sure they are aligned like they should be, and DON'T press them on too hard at first, until you like what you see! Good luck!
