Don't forget that the Tattooine garage scene had some added shots. The shots before and after were trimmed as well, so they would need to be replaced as well.
Those two shots are available on the second disc of the DVD release (I don't remember exactly which video), but they were cropped to 16:9. Those are the only shots that should affect the run time of the theatrical version.
btw, I would love to work on this if Team Negative1 has a scan lying around :)
