Tim, when I pulled my rear body panel off the sides of the body were very stout. I never moved the body around when it is was without the rear body panel but it seemed sturdy to me.
BigTony, I only removed the rear body panel so my body tech and I could properly repair the inner lower quarter panels. I never actually pulled the floor. But at that time I realized with a little effort it would come all the way out with just a little more effort.
