dynosaurus,
I recently purchased a radiator from
Patrick Antique Cars of Casa Grande, AZ. Patrick really gave me a good deal and I'll recommend him to anyone who will listen to me. They are a dealer out let for
US Radiators. I'm not at that stage of installing it but once I am, I have it readily available. The only thing, it didn't come with a cap. Still happy to have my old one replaced because it was so far gone that I didn't even bother trying to keep it.
On Track Performance is out of Englewood and they too are a dealer for U.S. Radiator, you might want to look them up and see what they can do for you.
