The SS-184A contains the same bracket as the SS-184.  The difference is the SO-239 base stud mount for screw-on coax connection.  There isn't enough clearance on the Dodge trucks to allow for this stud but, this mount works very well as a universal flat mount for bumpers, pick-up bed rails, etc.  Either mount is rated for antennas up to 4' (1.2m) in length.
