The last two posts are something to look at Eli. Stiff ball-joints need to be replaced anyway, so if that helps with the existing issue, so much the better.
I'm with BW too. Either your Bronco was even farther off than normal (not impossible) or you may have your C-bushings in backwards and they're fighting the drop brackets. That would help explain why you still only have 2° after all that correction has been installed.
At your point though too, adding the additional 1.25° of correction with the eccentric ball-joint collars would at least get you in the money from a "stock" standpoint anyway.
What are some other features of your Bronco? What mileage? What type, if any, power steering? What lift? Are you using a dropped pitman arm AND a dropped (or raised) trackbar bracket?
Steeper and/or uneven angles on your draglink and trackbar will also contribute to ill-handling.
Before you do anything else though, I would absolutely perform "the test" and have a helper turn the steering wheel back and forth. About a half-turn in each direction is plenty usually.
While they doing this, you're laying under the front end and watching all the linkages from the steering input shaft to the wheel bearings. Anything that doesn't look quite right to you, probably isn't. And there is ZERO allowable visible side-to-side movement in the trackbar and it's brackets/mounts. Same with the steering box on the frame. If you see movement there, you will need to inspect for cracks in the frame. Also, ZERO visible play in the ball joints as well.
If your steering linkage "rotates" before it starts to move side-to-side, check to see that each rod-end and the draglink are aligned with each other. You should get a very minimal roatational movement during steering movement.
There are other things too, but you get the picture.
Try that and let us know what you find.
