issue with AMD Demon floor pan..please help newbie

Ive been watching this thread for the last day or so. Did you "brace" the car before cutting out the old floor?? Could there maybe be a "twist" in the frame from a fender-bender maybe causing the issues?? I dont know, I just thought I would throw it out there??? Your getting close, and have way more patience then me!

thanks for the idea, i dont think there is any problem with the stucture of the car, i think the floor just needs some tweeking. its very close,
