WTF -- just looked at you pictures.
That gotta hurt.
there is a collision repair manual out there for the Alero. I can't recall if it got measurements but a GM dealership should get you on the road again.
If something like this happend to me, I'd be screwed. This would mean a new car for me - cause a new Alero would be cheaper than having insurance look at my car
that is sooo frigging sad
