Which gauges are you guys running?
69 Barracuda
Speedhut Gauges.
I will have to make adapter rings for the Speedo and Tach. They are 4.5" and the openings are for 5".
I like that you can select the font, tic line style, pointer style/color, night illumination color, bezel style.
GPS Speedo with Turn indicators and High Beam indicator.
Day Mode
Night Mode
GPS Speedometer has several cool features you can toggle through and reset with the button in the face.
This is the full set I ordered.
