Javelins have a thick, plastic-mesh style grille of miniature diamonds.
I love the grilles on the 73 and 74 Javelins, they give them a real mean look. You can't really see the grille on my car at all, but you may get a better look at it in my other section of AMC cars. The taillights are dual 'TV' screen shapes, the inner pair are reverse lamps. These also give the Javelin a very unique and cool look. The Javelin fender flares were added as a racing modification to make for better handling.
