The pentastars were put on 63s too. The later cars had them factory installed but the dealers recieved kits from Chrysler to install them on the cars they had already sold. You can imagine how many were called back in to get a tiny emblem installed!
The early ones were pot metal. Does anyone know for sure what year they switched to plastic?
In the 80s the star was resurrected in the form of hood ornaments.
2007 was when the design reappeared with a crisper design and brushed metal look.
