I am getting close to removing the body from the frame of my 31 Sedan and sitting it on a wood dolly so i can work on it. I don't plan on removing the sheet metal skins from the wood frame of the body since the wood frame is in very good condition. What, if any, bracing or shoring should I do to the body to keep it from moving or distorting when I get a few of my friends over to help lift it off of the frame? Or, is this something i should be concerned with at all? I plan on leaving the doors on the hinges and closed so that will help also until I get it set on a wood dolly.
Thanks.

If the wood framework is in good condition, you should not have any problems removing the body without any major support. It might move a teensy bit but nothing serious. I suggest putting the body on a flat, stable support while off the frame.

Thanks Chipper.
