Most of my V8-60 axles are missing these special bolts. I'm not aware of anyone making these, so I decided to tool up and make some, and make extras while I was at it. I sold out of the first batch in one day, so now I have more available. These are exact reproductions of original, and I have them in 1215 steel, and 304 stainless. They come with the correct castle nut and Cotter pin. $50pr shipped for steel, and $80pr shipped ( to lower 48) for stainless. These are of highest quality made right here in Sunbury OH.
