If you have a NAPA in your area, I would go there first. They've came up with all kinds of stuff for my truck. If all else fails, could you grind off a little of the shoulder on the one you found at your local store so that the drum would clear?
That's exactly what I did today. I chucked the studs in a drill and put them to the grinder.
The part # I used is Dorman 610-730. They are a little longer than stock but not much.
