for $50 you cant go wrong...unless he uses the wrong adhesive...make sure its the CORRECT 3M stuff...(Super Trim Adhesive #08090) NOT (General Trim Adhesive #08080)
*edit*, i read it wrong, i thought you were asking how to get them out, but you bovisouly got them out if you have the headliner our
the visors come out with the two screws on the one side, once you drop the one side, the bars will fall out. you will also have to remove the plastic holder on the other side. just pull the tab down halfway (you will feed it) with a knife or something, and then yank on the piece. the visors have a long wire on them, and the connector is way up under the headliner.
