Steering Column Floor Seal is installed in an area that is susceptible to damage from heat. If your steering column floor seals have never been replaced, an inspection may reveal a cracked and broken seal. These heavy gauge reproductions will last for years. #598 will work on any 1955-1956 Chevy model with a manual transmission. Note: This floor seal requires five #611 firewall pad grommets to install and a #232 steering column firewall seal should be installed at the same time.
