Looks good.
But I'm curious of one thing.
The long bolt and spacer and one of the shackle like parts I know would be to drop the right side of the diff assembly (Right side when sitting in the vehicle).

But how does the second shackle part drop the left side?
when I looked at mine it is hanging off of a mounting perch on the frame. Can take the bolt right out and it will just hang there. i would almost think another long bolt with a spacer would be the ticket there to relocate it under the perch (Might not even need a spacer.....)

But I've not torn it all apart fully for any reason, so I may be missing something. <img src="/forums/images/graemlins/wink.gif" alt="" />
(I tried dropping the diff on the left side to get my lift in like i did on the right, but could not by just removing the bolt so I pulled the CV axle instead to make install room.)
