Body Flex

[4OfaKind]

My 56 Chevy 4DR Post shell has been sitting on jack stands for the past 4 years. Nothing is on or in it. No doors, no fenders, no hood, no trunk. Just the front and rear windshield. I am close to finishing my tube chassis and so I am turning my attention to the body. The floors from the firewall to the rear bumper needs to be cut out; rusted pretty bad. The rockers are'nt much better. I plan to cut the firewall out so I can set my SBC back some.

OK my question. I want to weld in an X brace across the interior from each corner of the post behind the front doors before I cut out my firewall and floors. Do you think the body has flexed much the past four years since it has not been bolted to a frame or am I being paranoid considering this IS a post car? (Rookie Jitters)

Thanks for the help guys. I am anxious to see the body on this tube frame.
