      Construction and Appearance. Manufactured from heavy-duty 7 gauge steel, this core support mount is laser cut, bent, and welded to precise OE specifications. It ships with an oil protective coating to prevent oxidation during transit, and it is recommended to be protected further with Rust Buster Rust Converter Paint for enhanced corrosion resistance.
