Based on experience in my own panel truck project, you'll need to factor in the
set up and measurement time when doing the floor/toe panel/inner/outer rocker
work. All of these things at once is not insignificant.
They will have to also use new floor supports under that floor. That's what the body bolts run through, so it all has to be in vertical and horizontal alignment so the door posts/doors/inner fenders end up being where they need to be and fit properly .
They may need to weld in temporary supports for the body before they begin, to maintain proper alignment. If your hinges need work or replacing .... now is the time to do it, so it all fits good after all that nice new steel is welded into place.
