I was working on replacing the front cab supports tonight and it turns out the section of the rocker that the support bolts on to is rusted as well. Does anyone know what patch panel this is? Is it #7 in the lmc catalog link below? I've circled the section in red in the diagram below that I am talking about. Thanks for the help.
