I used sunpro gauges. I used their website as a reference and then gave those part numbers to advanceauto. they got them next day. I've got the electric oil pressure gauge but they have a mechanical that looks just as nice. i went with the electric to avoid possiblity of the tubing line springing a leak. I also threw in a sunpro hour meter and amp gauge. the amp and oil gauges light up when the headlights are on.
