trudyduster,
They are not making them yet. I got a used one at Carlisle Nationals last year for my 74 Duster. People know they are not making them yet and tend to ask a fairly high price for them. I'm thinking about going with a different radiator and would not be able to use the bottle I have now and would consider letting it go. The one I have is not mint but is in very good condition. Would you be interested?
