body/tub support how to?? replacing floor,rockers.........

[DURRTY]

I finished separating the frame and body. I have all the sheet metal I need to replace the floor rocker boxes inner outer rockers pillars etc. What have you done to support the font half of the body while replacing all this?? My frame and axels are going out to be stripped sealed and painted. and it seems much easier to work the body while its up and off the frame. I am going to put the top on it and line it up and move the bracing inside so i can put the doors on for alignment when needed. I have plenty of HD steel saw horses that i can cut and change the size of as i need. I don't know were to support it so that its secure and also going to keep the body as straight and level as possible. thanks for any of your ideas and help.

here are some pics of what im working with now. BTW its not on those jack stands now that was only temporary its fully supported by saw horses.
