Freightliner Cascadia antenna mount for the passenger's side spot mirror. Installs into an existing bolt hole, simply remove one of the bolts that holds the spot mirror in place (or if there isn't a spot mirror, just remove one of the bolts) and install this mount in it's place. Provides a grounded, tall mounting location for CB or HAM radio antennas. Also works great for XM or Sirius antennas due to it's height.
Fits in place of M6 mounting bolts on the passengers side spot mirror
