I changed them out years ago and don't have the part # but I had a local napa look up the 14mm stud knurl size and length, and then looked in the book for close size and found some and they ordered them and worked like a charm. No help with part # but that's what I did and they had a book at napa and were able to look up studs by thread size and it was sorted in knurl diameter to match it up.
yeah when I converted the truck from metric to 9/16 I ran a dodge ram slip on rotor and made new caliper mounts and it worked great. Ditched the press through studs holding the drum/rotor on and went with a slip on rotor setup. Worked great.
