I'm currently tearing my 59 Apache apart so I can get the body work done. I have the Bed off the frame and I want to next start with the Cab and front end. I will be taking all the glass out and doors off..At what point would Bracing the cab become important. Would I only brace the cab if I were replacing sheet metal and doing welding or should I brace the cab regardless? I don't want anything to twist or become out of whack.
