I mounted 5" round blind spot mirrors off the upper corners of my roll bar on the drivers and passengers side. I just made an L bracket that bolted to the rollbar and then the mirror mounting post went through the other side. WORKS GREAT and has passed the exam of cops in Salt Lake City, Highway Patrol and the 4x4wise cops in MOAB!! They are up out of the way of grabbing limbs and rocks! They also let me see all of the area behind me and down to my rocker panels!
