Ford kit, goes on sale for 20-25% off, and you can use your Ford points, that you get with Purchase of your Bronco. Costs $662(?), when it's 25% off. Free shipping to some dealerships, doubt that the case in Alaska. Most aftermarket kits exclude the gas tank skid, and they usually cost $600 ish for that skid alone.
It comes with nothing if you have the plastic bumber. As noted above the ford kit comes pretty cheap with discount code. The fuel tank skid seems to be the one folks say is actually pretty good. I ordered that kit but ultimately returned it and purchased IAG components.
