If I were you, I would consider an AC 65 Riv radiator. There are a lot more out there. Alternatives would be to send your core to an experienced classic radiator rebuilder. Chances are high that you will need to do the same with any new core unit that you may find.
Contact Larry Daisey, he's also in AZ: http://www.rivparts.com/meet-larry.html Larry Daisey is a unique guy. He is "old school" in his methods, but they are tried and true. He was once blinfolded and handed random bolts off a 65 RIviera and he identified them all. He figures he has owned over 100 first gen Rivieras and worked on over 1000. Point is: You won't find a more knowledgeable guy anywhere. Best of all: He's honest and a nice guy. Rust Free and Good Condition Our parts come from rust free desert and western cars.
