This may not be the right place for this, please move if I did something wrong.
I replaced the radiator in my newly acquired '64 1/2 because of overheating and it was obviously plugged with rust. After having it rodded to open it up and clean it up, I am wondering if it could be an original part. It seems to have a 1964 part number but I don't know what the rest of numbers mean. It was built the first week of June, 1964, here is a picture of the stamped numbers on it: Any help appreciated on whether I should keep it or even reinstall it for judging.
