I actually have a choice of 3 round top radiators - a 2 core I bought from another member that looks good but unknown condition BUT came with that elusive factory shroud. And a pair that I had a local radiator shop make each into a 3 core for me awhile ago, even before I owned the wagon (they were for another 65 Dart and a 65 Barracuda both long gone). I will use one of the 3 core radiators with the shroud from the 2 core radiator. Neither of the 3 core radiators has ever had fluid run though them except when he tested them after installing the tanks. They might or might not be correct for the wagon, but that’s OK
