I had a local radiator shop build a new heavy duty 4-row radiator for my old 454 dually. The original was plugged up. They built a new core using my old tanks and kept the in-tank tranny and engine oil coolers too. Worked great.
We recored in 2007 and the radiator recore for the part was $450. Was thankful to have it to help better to keep the coolant, oil and ATF cooler on our cross country trip.
