About frame reinforcement at the time of restoration.

Hello! The roof has come off while the body is being restored, and we will replace the quarter panel, speaker panel, trunk floor, left and right doors, etc. Is it necessary to reinforce the frame with pipes like this picture when working from now on? We plan to work on the ground without removing the tires and chassis.
thank you for reading it until the very end!
