My friend has a 1978 Dodge Motorhome with the 360 Engine. The MH is broke down in the center of his driveway and he needs a spark arrestor (for the ignition system) for it. He has been told that the part was only made for 74-79 and is not available. Basically, he was told GOOD LUCK by the dealerships that he called. Can anyone help out with where I might refer him to. Thanks Guys- If anyone can help I know you can- Take care, Ron
