I have the Cadillac disks on my Camaro and had to get longer studs also. I don't have the number and would be different anyway since the buicks use metric threads. But I knocked one out and went to the part store with a micrometer and searched through the hardware bins till I found the right length. A good parts guy could look up diameter and length and find the correct one without the old stud, but finding someone competent is hard these days
