Danchuk 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. Danchuk #599 will work on any 1957 Chevy model with an automatic transmission. Note: This floor seal requires five Danchuk #611 firewall pad grommets to install and a Danchuk #233 steering column firewall seal should be installed at the same time.
