I saw a similar solution recently in a thread on this site. I have included a couple of pictures.

Thats a nice solution! my concern was like you said the single sheer, and the fact thats in aluminum.. Aluminum has a finite fatugue life, meaning that it will break from metalfatigue eventually. when is only a function of load and number of cyles... (so while it might last long enough for 100 races.. it might not do 100.000 highway miles..) its also the reason that the spindles have a service life specified by GM, and why aluminum connection rods arent used in street engines..
The pic you enclosed shows nicely how the bending stress in the aluminum is eliminated by that bracket, AND that the load is distributed to 3 bolts instead of that one shock stuc
being a soon to be owner of a c4 rear end
id love to hear where you got that bracket?
