[jet-taz]

is the block for the rear brakes the same on a 81/4 & 8 3/4 .the one i took off an 81/4 doesn't have a vent screw and the 8 3/4 didn't have oneon it.i got a vent screw on it's way.but was question the block it's self. thanks jet-taz

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

I don't know about the 8 1/4, but the one off my old 7 1/4 bolted right up to my 8 3/4.

did yours have a vent top? and is the bolt hole in the block the same size?

[qkcuda]

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.    Mike

well i got my vent bolt(it's  mopar 04032798) it fits the block from the old rear from the car, but i need to see if the blocks themsleves are the same.
