I bought one of these....

when we bought the Fairlane years ago. I wanted to be able to remove the filter for cleaning without having too pull the hose. Previous owner ran straight water in it for a while so the block is rusted badly. Pretty much pulled it out and cleaned it after every drive. Don't remember the details but when I had the radiator rebuilt I found a guy that had an old core that had a different type of fin on it, hate like hell to plug it up again....
