Need a new set of running boards because mine are pretty beat up. No way a paper gasket is gonna fill the gap, so I traced the shape onto extra thick motorcycle inner tube. You can get them 4-6mm thick and probably thicker than that. Even standard inner tube would be better for my purpose than the paper gasket.
