I have accumulated a few of these gauges over the past year when aquiring some cars. They all functioned when they were pulled. I have no use for them, since the Phantom ones are the wrong face color and the "sport comp 2" one only goes to 20psi.
Anyways, They are the 2-1/16th size.
Phantom:
Boost- 30in/30psi: $40
Narrowband 02: $30
Voltage: $30
Sport Comp 2:
(this is an LED lit gauge)
Boost: 30in/20psi : $40
Thanks!
