The sideview mirror on my cousin's '02 IS300 just broke courtesy of some punk's idea of having a good time. As a result I've bought a set of racing mirrors which I need to install. Without breaking anything or scratching anything up, does anyone have instructions on how to do a general install for these side view power mirrors? Basically, need hints or instructions on how to get access to the screws inside the door panel, etc. to remove the old sideview mirrors and install the new ones. Thanks in advance.
