Here is a  used OEM  grille.  It was removed from a 1963 Plymouth Belvedere.  It is in decent shape, with just a few areas of concern. On the horizontal bars in the center section,  there are two that have a slight bend in them, see pics.  They could probably be straightened, but I didn't want to mess them up more trying.  On the backside, in one corner there is a metal mounting tab missing, see pic.  Be sure to check out my store, as I have lots of '63 goodies for your car!    And remember, shipping is FREE in the lower 48!!!!!!!!!!
