I am just about done installing a complete foor pan in my 69 convertible, next comes a complete trunk pan and frame rails. my question is does anyone know the best way to support or brace the car to do this.It is on a rotisserie now and the rear is bolt to the bumper mounts. Any ideas would be appreciated. Thanks, Roy

I would make a frame to go from the rotisserie frame up to the rear of the rockers. Tack weld it there or bolt it somehow. Also I would do the same in the back and bolt it where the side bumper brackets bolt to. Take measurments at the rockers and also a good reference point on the back. Mantain those while you replace your parts and everything should be okay. You won't be able to rotate the body but it will be stable.
