You can get a Modine radiator through a parts store, such as NAPA, that is fine for normal street use. If you are racing or doing a lot of agressive driving, then a custom radiator that is built to match the cooling efficiency you need, for the type of driving you do, is in order. I think Modine was one of the OEM suppliers for the radiators, but I'm not sure of this. Any Ford purchasing agents out there know if this is correct? Hope this helps, rangerj
