Bad idea?

I would like to add a couple of questions: 1) Should the windshield and back glass be removed before rotation? (I picture glass cracking from stress movement) 2) I think I have seen pictures of convertibles tilted that had some kind of crude tubing welded into the door openings, is that necessary and if so, what is the procedure? Thank you, interesting post.

I don't think removing the glass is absolutely necessary. Depending on what kind of work you are planning to do. If you have a car that stripped down, I would think you'd want to remove the glass just to inspect/repair the window channels These cars are uni-bodies with the heavy rocker panels and roof structure forming a box. With the body stripped of all bolt-ons I don't think they weigh enough to worry about popping glass. At one point I was wheeling my car around like a wheelbarrow by myself with only the rear axle in place.
