Hi everyone. Anybody know what size tubes and on what centers 22" big block Dart radiators originally had from the factory? Also how many cores did they have, 2 or 3. I'm looking at a aftermarket rad from a vendor called Windy-City Muscle and trying to decide if the radiator they offer will fit between the fan and the radiator support on a 69 440 Dart. They clam its a exact bolt-in fit (same as the original rad) and looks about the same as the original too, but it has 4 cores with 1/2" tubes on 9/16" centers. Core dimensions are 17&1/2" x 22" Has provisions for the factory fan shroud it looks like also. Not looking for a aftermarket alum rad so please don't go there. This one is brass/copper and looks more stock. Any help/opinions would be greatly appreciated. Thanks.

Talk with Bob at Glen-Ray Radiator and he will tell you. I know for sure that the original radiators have 1/2" tubes.
