I added three, engine, transfer case and fuel tank (plastic skid plate). I will see if I can find the part numbers, it might take a day or two (they are in my shop some where). If you are planing on doing anything that needs skid plates and have the ablity you might consider making your own, it is on my list even after buying factory. If you want and are not in a hurry I will take some pictures so you can see what I am talking about ( I am assuming I can post pictures, new to the forum)
