Just an update for anybody interested, I have finished the rear suspension aside from the swaybar and have started on the roll cage.

I'm sure you are way beyond the pics here, but with all the discussion/concern with loading on the upper 3/4" link 5" bolts, I noticed the pictured upper TR located approx 75% off center of the two upright brackets, the loading would also follow that offset I suspect, but the outside bracket is axle clamp restrained on a cantilever welded bracket. Seems slightly edgey for lack of a better word. Is that what you had as your final result?
A number of things have changed since I posted those photos, jobs, priorities, and other projects (mainly a 410 sprint car). Unfortunately the car hasn't and is in essentially the same state pictured. I have looked at the 3rd link and thought it over more than a few times and have deemed it insufficient and in need of a redesign or removal.
