looking for a 68 dart grill and headlight bezels

The headlight bezels are totally different so your 67' stuff won't work. If you find someone willing to trade 67' stuff for 68' stuff then you better jump on it. It isn't very likely. Check out e-bay for a grille. Most of the time one that is straight and in need of polishing and re-painting brings a few hundred but a week ago there was seven put on in a 24 hr. period. I was able to score two for less than $150.00 for the pair including shipping. It isn't likely to happen again but you never know. Good luck, Scott.
