The Stingray tail lights get smaller as they go toward the center. The Camaro tail lights stay the same size. It looks like right below the spoiler is a thin straight bar and a bar halfway below each tail light as well on the Stingray. The bars would make it easy at night but the slant will at least give you a fighting chance on a guess. During the day the exhaust is a dead giveaway since the Camaro is the outer edges and the Stingray centered.
Besides, the old Camaro (think 1970) tail lights were circular back in the day as well.
