I received a good price on a G5 because it had beed dropped which bent the right rear base/foot. Now there's an 1/8in gap between the top of the base/foot and the body toward the rear. Apparently a grommet broke. Other than that gap the G5 needs to be shimmed or it will wobble. Has anyone ever done bodywork on a G5 case? Is there some DIY possible or is there a profession in the yellow pages that I could turn to?
