Can these Fast backs be saved?

Can these cars be saved? Looking to make some drag cars and wondering if anyone has done or replaced roofs for our cars? AMD make them or can it be done doner wise? Probably may need new pillar arms also. I can do any type of body work/rail replacement but never got into a bad roof or anything like this. I have doors and few other good parts for replacement. Anything other than a fish roof fit our cars?
