I’ve had a close look at this topic, see : 1970 Eliminator Blackout Reference Info but I cannot find any detailed explanation about the stripe on the reverse light bezel / housing or the trunk lid molding ( as in - does it wrap around ? ). There is a mention about the 1/4 panel extension, but that seems to be about it for the blackout treatment with regards to this specific area.
Maybe someone else can add this detail / provide an image ?
