If you're going to save the car you're going to have to cut the roof.
X2- that car better
really mean something to you if you are gonna put that much work in it. Most professional body shops wouldn't even attempt that. You will have to weld in temporary braces all through the interior to keep the whole car from collapsing and becoming an unrepairable mess. Then remove the windshield and rear glass. Then sawzall the roof off at the lead seams, and weld a donor roof back on, Taking measurements all along the way to make sure it's lined up all right, so the windows fit in and doors shut properly. It will be a pain in the *ss no matter how you do it. I'm not trying to discourage you, I'm just being honest.
