26 inch radiator in a duster?
I used a 27 inch radiator from a big block Cordoba in my '72 Duster. It did require some sheet metal mods to fit since my car didn't come with the bigger radiator. My 512 street engine stays nice and cool with the factory big block radiator and shroud. So it can be done, but if the car wasn't designed for the larger radiator then you'll have to make some modifications.
