I got the rugged ridge relocation brackets which use the lower of the two sets of bolts on the windshield hinge frame thingy. Like this:
I didn't like 'em at first because I couldn't see anything but about 1 square inch of my passenger side mirror with the doors on. I put one of those tiny "fish-eye" mirrors in the bottom outside corner of the mirror, and that helps a bit, but I still do a lot of looking over my right shoulder when merging. I DO however like the fact that the mirrors are not still on my doors and that means my doors fit in my living room closet, right next to the hood off my Camaro. I promise that I'm not as much of a white-trash hillbilly as this makes me sound.
