Radiator Fan and Shroud Mounting dimentions.

Can anybody here tell me what the mounting hole spacing is in width and height for an F body fan shroud and radiator for the V8 AC max cooling set up. I am trying to find something that will actually fit my fan shroud on my dart. All the aftermarket radiators sold by the pars stores are too narrow to fit the original fan shroud. They measure about 25" and the shroud mounting holes are 26" on center. The F body replacement radiator is wider but I need to know the mounting dimentions for the shroud and radiator to see if I can fit it.
