I needed some studs that go into the axle housing flange, which are used to hold the bearing retainer and backing plate, to the housing. These are the same on 7 1/4, and 8 3/4 rears, and I would think the 8 1/4 also. These are also used to mount the center section of an 8 3/4 to the housing. I don't know if they are available from Mopar, but, your friendly Ford dealer has them. Part number EOTZ-3C140-A. $9.12 for a pack of six. I tried to put this in the parts data base, but it is down, again.
