Trying to sell a air breather I bought off e bay a few years back . It was suppose to be off a 70 Challenger for a 4 barrel . Well it does not fit a 4 barrel and I can't swear what it goes too . I just kept it at the time rather then screwing around . The carb hole is 4 inches around . If anyone is interested I need $60.00 plus postage , that's what I paid . Thanks
