If you own a classic squarebody, then you know that they typically leave you battling with rust at the bottom of the door. Well no need to worry because BROTHERS Trucks is here to back you up with our replacement bottom inner door panels for the 1973-1987 C/K Series trucks and 1973-1991 Blazer/Jimmy/Suburban. The inner door dottoms have the OE factory shape and lines, as well as better corrosion protection due to the EDP coating. They are manufactured with heavy gauge steel for superior strength and have the quality that your project truck deserves.
