65 Dart GT Fan Shroud
If the 65 has the 22 inch wide radiator the answer would be yes on a factory fan shroud. I sold the one I had last year to another member here. It mounts to the side of the radiator with offset brackets. The radiator opening was enlarged in 1965 to accept the 22 inch radiator but I don't know if the radiator just had wider flanges and still the 19 inch core on the slant 6 cars. The 273 cars had the 22 inch wide radiator.
