1997 Toyota Land Cruiser & The 1996 - 1997 Lexus LX450 models ONLY. Power antenna mast kit. If you can still hear your motor working you should be able to install this and be all set. Replacement instructions: Unscrew the top nut. Extend antenna mast with interior switch. Everything will come up and out. Then feed in the new mast and retract the antenna. You may need to let it go up and down a few times to wind up well.
