Good Morning, I just read through your thread and it looks like it will be an awesome build with your son. I still have a 46' Ford that I rebuilt with my father in High School and still drive it to this day! As for the body, it only took four of us to lift it off and one person to roll the frame out from underneath. I also removed the from clip so the body wouldn't have to be lifted so high and it was lighter. Hopefully I'll get back to mine in a bit, and I will definitely be interested to see how yours turns out.
