My wife always complains about the sun in her eyes so I bought a pair of these visors and only modified the passenger one to fit my car.
All you have to do is dremel down the mounting bracket to make it fit a GD. I havent tried to make the light work yet but it should be pretty simple I would think.
drivers side extending visor only... $50 shipped to continental US. PM me for my paypal address.
here is video of my passenger side one i mounted. (Sorry about the heavy breathing... I was sick the day i took the video and it was hard to breath)
