I'm wondering what everyone is doing, besides "putting a Dana in it" or a "9 inch"

I stumbled upon this 8.8 brace setup on my buddies car,and I'm thinking of doing something similar that attaches to where the pinion snubber plate bolts to, and attaching it to the axle housing similar to this.


Has anyone ever done something similar or different.

I don't see how something like in the picture will help what plagues the 8.75 by design. It's done that way on an 8.8 b/c you can't really put a backbrace on it. That just keeps the housing from flexing, not the centersection.
To "fix" the 8.75, you need to somehow keep the pinion gear from moving away from the ring gear under load.
Instead of spending money trying to make my 8.75 live just a little longer, I replaced it w/ something stronger.
