Combination Gauge Firewall Grommet
If you are replacing you combination gauge, you may be missing the grommet in the firewall for your sensor wires. We are happy to offer it here, if you need it, or a complete firewall grommet kit which you will find here.
NOTE: The combination gauge grommet is NOT included in the firewall grommet kit.
If you would like a Smith's gauge to install, find it here.
