Check with Patrick's Antique Autos. I think I remember talking with him about one but not sure. I was having my engine machined and the shop broke the existing one on mine. They located one pretty easy for about $8.00. You might want to check with Napa or Carquest. You would be surprised what they can find. I am going to my machine shop in the next day or so, if someone else hasn't helped you by then, I'll get back with you. Good luck
