I want to run a ram air set up on my 66 belvie like the one on my old car (see picture) my plan was to use a 67 grill with the 2 big bulb openings. Are the grilles the same fit? Will the center grill from the 67 match the 66 bezels in fitment? I was told the bulbs are smaller in the 67's - anyone know the diameter of the inside opening for the headlight in the 67? If the grille and bezels will not match up between the years, will the 67 grille and bezels together fit exactly like the 66 ones (and I would just run the smaller headlights)? Sorry so many questions just want to know how to approach this and I know one of you guys will know this.
