A V8 radiator won't work. You can find I6 radiators on eBay also. I got my new radiator from Advance Auto Parts just as cheap. It was listed for a 64 Falcon, but fit my 61 after bending the lower bracing to the radiator support. The new radiator was a little longer below the mounting nuts than my stock 60 or 61 radiator. The radiator is also thicker. My fan is now very close to the radiator. I am using the 6 blade metal fan that was used with A/C equipt cars. Everytime I start the engine, I hear a noise that sounds like a fan blade hit something, but I have not developed a leak. I need to get an even thinner profile fan, or modify the radiator support to move the radiator forward slightly before I do wreck the radiator. It does run alot cooler than before.
