Speedometer & Floor Shifter Cable Grommet
وصف
This rubber grommet fits 1964–72 GM A‑, F‑, and X‑body vehicles and seals the firewall opening for the speedometer or floor‑shifter cable to prevent chafing. The flexible material protects the cable from rubbing on the firewall's metal edges and helps block dust and moisture. Its design follows original specifications used across multiple GM platforms. This grommet replaces hardened or missing originals that commonly deteriorate over time.
