I have a 2019 Rubicon with a plastic bumper and I have just purchased a Mopar Steel bumper. Im looking at the skid plate mounting brackets and they look different than the ones in the instructions and there are two additional holes with welded hex nuts to the verticle side of the plates. The parts department at the dealership are clueless. It does not look like the plates are a proper fit for putting on the steel skid plate and looks like too much plate. Has anyone else encountered this? I don't want to spend an hour taking the bumper off just to find out these plates don't work, Suggestions?
