Are you fighting rust on the inner rockers AND it is now starting to make its way into the floor pan? Holley Classic Trucks has a single solution to both problems with our outer cab floor with inner rocker panels for the 1988-1998 GMT400 Series trucks. These new floor panel/rockers have an excellent fit just like the OE, 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 and fit that your project truck deserves.
