As I was taking my last cruise with my '66 Sunday evening I notice the windshield fogging up on the passenger side and a whiff of antifreeze. So as expected once I parked it, the heater core has a small leak. Luckily this is an easy one to remove. I also noticed a little dampness on the engine side of the radiator as well. Since these are all original it makes sense that this is happening. So.... do I buy new or take them to a radiator shop? This only has the small 289 in it and I don't have any plans to put anything bigger in it. It's not a show car....its a cruiser for the family. What would you do?
