Years ago I fought with all kinds of mirrors. Close the door and it's looking at the running board or up in a tree. Can't see anything out of them without bobbing like a boxer. Then I stumbled on motorcycle mirrors. Drill a hole in the window frame where you want the mirror, take off the garnish molding on the inside and drill a larger hole to put the nut on and....done. Matched set of mirrors run $15-$20 for functional non billet chrome. Works for me!
