Ouch! I'm following your original thread (and sorry to hear about this, BTW!), and looking at the damage to the frame (last photo above), I wonder if the k-member is okay. Obviously you'll be tearing everything apart and will check this, but I'm really curious as to how much damage, if any, it sustained.
Good luck with this, and has been said before: Thankfully no one was hurt, and all of this is just "stuff", when you think about it, and it can all be repaired.
