Just a thought on the subject, if frame connectors would've been installed at the factory when would they be installed, during construction of uni-body before suspension or after the install of drivetrain and suspension sitting on all four wheels after paint. It makes sense that it would be during construction of the uni-body on a jig. So it seems that if fenders, doors are aligned and frame is level and all that you would be fine doing it on a rotisserie or on jack stands. Just a thought.
