You must first decide what extent that you want to do your restoration before you start. In my case it was the only way to properly and thoroughly do what I need to do.
I wanted to design my rotisserie so that the car will be supported at its strongest points, which are the spring boxes and at the front cross member. In locating the centerline of the car enable me to rotate the body by myself with ease. And last, Installing large lockable wheel casters provide mobility to transport body to the paint booth. I have since join each end of the rotisserie to add additional stability with 2” tubing that’s bolted to each support.
