A little help to verify what I am thinking?

The split strut rod bushing probably explains everything. With a strut rod loose, caster and toe-in will change erratically. It will not be safe to drive. You mention oversteer (turns more the more you turn the wheel) -- this is extremely unsafe. I once spun my Barracuda 270º across 3 lanes of US 101 in Mountain View because of a split strut rod bushing (punched it coming off the ramp); wound up facing oncoming traffic. Miraculously, nobody hit me. Don't try this at home.

More free advice: just because you found one thing broken, don't assume nothing else is broken. The bushing is probably a hint that all the front end consumables are pretty worn out. They tend to get replaced all at once "while I'm in there".
