[HO LEMANS]

Ok this may or may not be a dumb question but I need a knowledgeable answer so I am here... I have a 69 Lemans and at the moment it is just a shell (with solid floors) on the frame and I am wondering if I use my cherry picker through the door opening and attach it to the seat belt holes in the floor to lift the shell am I going to damage the body ? I want to get it off the frame and onto my rotisserie but I don't have access to a forklift or anything like that so this was something I thought might work but, I'm terrified I may damage something in the process.
