I saw where this question was sort of answered in the past but I have a little different take on it. I have a 73 Cuda and would like to just swap in the 71 grill but keep the single lights as is and in the place of where the 2 innermost lights are on each side, put duel air intakes. I would want to leave everything else alone. I am not trying to make a 71 clone, just want to swap out grill for 1 with existing holes for the intakes. Anybody have a take on difficulty of this? If it requires a bunch of extra work such as switching out bumpers, etc then I don't need that aggravation. Thanks in advance for any advice.
