G'day Folks
Almost the same bumper,the holes are in the same place all 4 of them, but. the late 2a lights in guards the bumper is slightly wider and the verticle bar spacing differs slightly to allow the headlight to be in the correct aperture, the early headlights in radiator panel up to and including Suffix "D" is 1520mm and the later Suffix "G" headlights in guards is 1600mm so the later one is 80mm wider.
I have both and have just gone out and measured
