Maugan VX - I bought some blind spot mirros at Pep Boys that are actually designed to fit on the mirror mounts of GMC trucks so that they can see up and down better (as oppossed to our problem of side to side). When installed sideways on the outside corner of the mirror glass, they offer a two-fold benefit - you can see the blind spot in the next lane PERFECTLY (I don't even have to turn my head for lane changes anymore!), and you can also see the ground right next to the car, which is a big help when backing out of a parking space with a curb next to it - no more worrying about curbing your tires/wheels. I'll get the part number the next time I'm at Pep Boys and post.
