I did it and wasn't so bad. After done I took the car to a paint shop and he said he's had guys work for him for 15 years and didn't do as good as a job. I was happy. I simply took a bad saw and cut right under the front pillars (so I wouldn't have to bondo after welding it in) and saw sall the back pillars. After placing the new roof I had a pretty good gap so I put filler piece metal in and just welded and grinded until close and bondo until looked right
