maok Posted February 7, 2020 Report Share Posted February 7, 2020 I purchased it at our large annual swap meet, can anyone identify what car or truck its from. Only markings on the back are AT-5001. The two nuts have insulating washers underneath and the two screws don't. The long threaded posts I assume are mounting studs. Quote Link to comment Share on other sites More sharing options...

I wonder if that radial switch (1-4) is to adjust for different cylinder engines,ie., 2,4,6&8 cylinders? Quote Link to comment Share on other sites More sharing options...
