Speedometer Cable Firewall Grommet for 1967-1973 Mustangs.
This correct replacement speedometer cable firewall grommet is manufactured using the original Ford blueprints and is a direct replacement for the factory grommet.
The grommet fits in the firewall and protects the speedometer cable from being damaged by metal edges. It will also keep out any unwanted engine fumes or moisture that may enter the car.
