The six and V-8 radiators for the 63-66 do interchange with no problem. The V-8 radiators had a much larger tank than the six, IIRC. The core support is identical on the 63-66 big cars, and is the same on the 64-69 American. I had a V-8 parts car, but compared the sheet metal in my collision parts book also. Hmm.... maybe I need to look at that some more! Might have some leads. Unless restoring a car, the tank really doesn't matter. For a driver, keeping it cool is the most important thing, naturally. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
