Steve,
Not trying to be a smart a$$ here but ...
Are you looking for longer studs because yours are too short or is this for some special application?
I see from your avatar that you have a 28 or 29 ... maybe you have "AR" hubs and are trying to use new wheels on AR hubs. If so the studs will come up short as shown in the SB page 328
Figure 662 shows the problem.
See Service Bulletin page 328
Sorry I guess posting pictures no longer works.
Hope maybe this will help
