My donor has a large number of miles and my radiator isn't in the best of shape. I am not thrilled with the center location of the top port on the radiator either. Does anyone have any suggestions on aftermarket aluminum radiators that will reasonably fit in place of the OEM unit?

My initial investigation has not found a similar size unit. Seems most of the aftermarket stuff is taller and narrower, meant for the typical muscle car. I am open to suggestions.
