I am making a similar one. My question is do you guys find that you need to brace the unibody on an a body so it doesn't twist when it is up in the air?
I think it would be best to remove the doors and install braces across the door jambs. Up in the air or how high isn't the issue. The problem is having the weight on the farest ends of the frame horns and then turning the body first one way then the other. Combine that with how long it might remain in an un natural position and it can't be good.
I may never get my convertible restored but I wont start by building my own equipment. My plan is to purchase a rotissirie and frame ties from U S Cartool. Here why... Imagine an ebay add that reads "U S Cartools Rotissirie, model # 3937836, purchased new June 2010. Used once , like new "
Compare that to " Homemade auto rotissirie. Works good."
Which one will recoop more of the investment is a no brainer.
Just my .02 Happy moparing
