12V generator with tach drive sold sold sold

I bought this generator quite a while back hoping it would allow me to use a mechanical tach on a project. If I remember correctly its intended use was on a tractor. It is unused and has been sitting here for maybe 20 years. It has a .104 square tach drive and no pulley. the shaft measures at .590" . I can't guarantee that it will fit any kind of car but I am willing to measure whatever you like before you buy it. 100 bucks plus 20 for lower 48 shipping
