55-57 Chevy Firewall Distributor Wire Rubber Grommet.
This grommet mounts on the firewall next to the wiper motor. The engine wiring and wiper switch cable runs through this grommet. If unprotected by a grommet, the hole where cables and wires pass through the firewall is often the start of peeling paint. Once loosened at the firewall hole, it is often difficult to stop. Protect that well-detailed firewall! Fits all 55-57 Chevy Car Models. Made in the USA.
