The one that I have on the 81/4 that is going in the fish is a lot bigger than one from an 83/4. I would think you could still use a vented bolt in it. Dave

Taz, I have the vent top and as far as I can recall, everything from the 7 1/4 fit the 8 3/4, but it was a long time ago when I took it apart. ( and I sometimes have trouble remembering what I did yesterday) ::)

my ole 8.75 used a vented retaining bolt for the brake block, my 8.25 and 7.25 both use a solid bolt, as there is a seperate vent tube attached to the housing as a vent. If you use a vent rather than a solid bolt, it won't hurt things, but don't use a bolt, where a vent it needed. jUst check your rear for the seperate vent. carefull with the vent-bolt.....then strip often....and use neversieze when installing it. that way you won't snap it off in the housing next time you need to disconnect it.
