If your dash looks like this, then this mount will fit.
This mount is designed to be able to mount 1 Graph on a Slider Type mount. You will be able to slide the unit up and down and also have the ability to slide the unit left and right which gives you ultimate adjustability. This mount also angles the graph more towards the driver for easy viewing. This mount works the best with a "Shorty" Type BBT Gimbal Bracket.
