Wow, you've done a lot. My only suggestion is that maybe the strap pull might not have been strong enough. I did a similar thing but with a steel cable come along, as described in this thread, with photos here:

You'd want to have the right things loose (e.g., leave the right side all tight if it is how you want it, loosen whatever it is on the left side that you want to move just a little), pull it tight, and tighten things down. Of course, be concerned with torquing bushings when out of loaded geometry.
Every fastener in there has some amount of clearance / slop. You just need a little movement to get 2.6* back in spec.
I'd do that and see what you get.
Another tip (I do my own alignments, which really helps) - to get faster feedback on whether what you are doing is helping is to figure out how to get an accurate camber measurement in your garage, driveway, wherever you are doing the work. So you can do it, measure it, and keep trying if needed.
