If my memory recalls me its as simple as adding a spacers to the top 4 bolts and adjusting the bottom to make true again.. could have been taken apart, cause i want to say when i helped a friend take the front off his Corvette both sides had shims on the top.. and he bought the car brand new.. so was never in an accident.

Any other thoughts? Based on my alignment print out? Toe is fine and negative camber isn't excessive but somehow my 500 tread wear rated tire is getting its inside completely smoothed out in just a few thousand miles...

Yep, upper A arms come pre-shimmed form the factory, so if you run out of range on the bottom adjustments, you either add or subtract shims on the upper arms to get the lower adjusters back into range.
As for being wrenched to cause the problem, could be that someone pulled the Arm for some reason other then the car being wrecked, and did not install the Shims back in correctly instead.

So upper control arm shins should be the solution??
Any other thoughts? Really don't want to spend the money on the shims / upper control arm and find out it's not the fix...

The type of driving you do has a lot to do with tire wear.
My 2 C6's got poor front tire wear even with neutral alignment settings since all my driving is slow speed city, in and out of driveways, parking lots and streets with many speed bumps.
Back tires looked excellant and front tire still showed decent aligment stats even with the excessive tire wear. You guys that drive highways/ freeways will get much longer front tire wear than I will with my city driving.
If you can't get neutral alignment (dead center of suggested specs, no + or - allowed) then you have a alignment problem. If you can get neutral specs and still have front tire wear then it might be your type of driving/streets.

I just got my car done today...had spacers added in the upper control arm and now both front tires' toe and camber are basically 0. Will put on another set of front tires tomorrow and see what happens in the next few thousand miles...
