Has anyone made or used a body sling to lower and raise the body on the frame? I will be building my 33 on my lift and after reading lots of posts I see the need to mount and remove the body several times. I can't always get help. I wonder if a sling would allow me to use a winch to raise and lower it by myself. I had bought one to do this for my 78 Vette restorod job I did 5 years ago. Any thoughts? Thanks. T.W.
