That's the way the questions get answered. Being that I have the frame rails as 2"x4"x3/16" thick plus the body will help with the rigidity especially in the back. In the rear frame section over the axle I will have adjustable bars under the axle with adjusters.
The front will have bars coming down from the firewall to the frame for rigidity as well. Sort of like what I had on the sled.
Notice these bars bolt on and have teflon pads between them and the frame and them and the firewall. I need this same structure in the body to keep the frame sealed and not flexing.
