Brass overflow tank for big block C3 Corvettes with AC

Very nice used original Harrison brass radiator coolant overflow tank for 427 and 454 big block Corvettes with air condition. I do not believe these have ever been re-produced, but this one is the real deal. It was pressured tested after I purchased it and passed. That is why most of the paint is gone. Comes as-is. It does not have the mounting brackets, but I have an original set on my car if you want to take pics and measurements. I believe they would be easy to manufacture because they are basically radiator clamps. If it is still listed, it’s still available.
