Hi all and thanks in advance for any help you might be able to give. I am putting a new heater core in my 1966 Dodge Charger. It is a factory AC car. I would like to know if anybody knows of a source or part number for the heater core tube o rings. These are used on the tubes that connect to the heater core bypass valve. I have never seen anything of this nature. These are the 2 copper pipes that stick out into the firewall and where they connect to the bypass valve it is a slip fit with an o ring inside to seal it . I have looked on ebay and on google and can't find any that say they are specifically for this model of Dodge. I have found some for late model mopars such as jeeps etc. By the way this is a very expensive heater core $275 and I am not going to use the air. Is there any way I could use a heater core for a non air car? They run about $75. Thanks, Dan
