Re: what is the 1975 c30 dually front wheel stud Knurl size?

Thanks for the reply I finally got my digital caliper working, the circuit board was corroded, they sent me the wrong stud. the stud they sent was .655. That said the stud they sent was the perfect length and thread. now I just need them to get back to me before I order the full set with the correct knurl size.
