The hood itself seems to be authentic, it has the correct features for a Challenger hood, there is a possibility that someone used one of the kits I used to sell to build that hood, they also had the correct shape and feature (no other kit or hood on the market has them right) but based on the assembly details I can see it's either a masterful installation of the kit or it's the real deal.

Most or all of those studs appear to be replacements on the trim ring, and accordingly are off slightly on the locations. The pics that follow are of a Cuda ring with all of it's original cast in studs, the studs should look the same and are in the same locations on Challenger versions
