I recently purchased some of these decals from what was said to be from the estate of a past Chrysler worker. There were many decals including "Air Grabber" and "Ramcharger" scoop decals, emblems and even some reflective Chrysler Corp. Fire Extinguisher stickers. All of the pieces appear to be assembly line or "Lunch Pail" items and are for 1970-71 cars. These New Car Prep decals I've never seen before and was wondering if anyone has any input as to what they might have been used for. Thanks in advance for any help.
