Click on "goodies of interest" to see the triple gauge.
They can also do quadruple gauges (adds a voltmeter) and custom gauges. I have had good experiences with them over the years, in fact my tach is there now to get a face lift (the orange needle had faded nearly to tan and the black face to gray).
I always try Pelican first, and they do have a gauge rebuild program, but I was told they don't do the cosmetic stuff....
