I have a 67 standard with a 79 351w installed. The previous owner had installed a aftermarket aluminum radiator from summit . The radiator is about 5 years old with only about 4,000-5,000 miles on it. It started leaking from the passenger side in the center out of no where. Im super pissed! If anyone has a radiator out there they are looking to get rid of, i would be interested if the price is right! Thanks in advance!
