Looking at some old post. This question has come up before so I guess I am not the 1st to come across this. Is the whole core support different? I do not have the car here so I cannot look at it. Can someone tell me what I would have to change to put the 26inch radiator in?? I still think the motor and trans match. But who really knows its 45 years old and like I said people do all kinds of stuff. Rebody fake tags cut #,s from one car weld them in another and the list goes on. It is too bad Mopar does not offer a service like Pontiac PHS. Then you feel a little better about what you are buying. Thanks again my Moparts brothers!!!!!!!!!! LJ My brain hurts!!!!!!!!!!
