Hi- I recently purchased a 1978 Class C motorhome on a Ford E350 chassis. I am restoring the motorhome and I really like the 1979 grille/headlight arrangement that includes the rectangular headlights vs. the round headlights of my '78. I realize that the parking lights for the '79 are incorporated into the grille area and that I will need to swap out the bottom body valance to accomodate this as well as the headlight buckets. Other than that, I am hoping that the grille will swap in. Am I correct or are they different in size and will not swap. Any assistance is appreciated!
