Correct Fan Shroud for a #2898027 Radiator 273

Hi! Barracuda 1968 273. My radiator number is 2898027.
Which is the right fan shroud? Which part number?
Not sure if it's the #2785614 ... cause it looks like some measures are slightly different.
Mancini Racing says that from hole to hole in the upper and bottom is "22.875, but on my radiator I measure 21,65".
