AMC Rambler Nash Hudson single headlight retaining ring. Will fit AMX & Javelin. This is a early model headlight retainer ring. It doesn’t have the place & twist groves in it. you would have to remove the three screws completely to replace your headlight. But they do line up with the AMX & Javelin headlight bucket screws, and probably other late models. This was in a parts shed of some one who is no longer with us. And everything in the shed had to go so I took everything that I thought could be to some use for someone. I don’t know what model or year this fits. See pic’s. If you know what it is don’t hesitate to tell me. Thanks.
