Looks like the car did not take the hit well, I love to repair metal but that car looks like tit needs a new front! We actually did that a lot in the body shop in the 70's, mostly rustangs and comono's, but I do recall one real nice 68 44 cuda the guy did pretty much the same thing you did. we found another which had been rear ended and a little cut and paste and walla, nice car. We cut the floors at the seams inside and at the front posts, measure real careful before you cut, then everything else is easy. Good luck, if it turns out you can't piece it back together the guys here will surely assist in removing the carcass, after all it is just a car. Glad you are OK, good luck.
