Ok i used the dry ice method today on the floor took about 2 hours . I read online that you break it up in little pieces and move it around but it was much easier for me to have one or two big chunks and slide those around. As for rust not to bad thought it was going to be a lot worse . So i will cut some panels out and por15 the floor .



I also weighed out the big chunks some of the pieces turned to dust after hitting it but got most .This is just the floors not the tranny tunnel. So 16 pounds not to bad.
