I think Skid row makes one but I'm not sure if it's for YJ's. Turbo City makes one that is universal. Unless you're driving jstu dirt roads, it's not a good idea to use the oil pan as a skidplate. Puncture that and you're SOL. Not to mention it could be really expensive if you don't catch it right away. Although, if your Jeep is lifted, it would make it a lot tougher to damage.
