Same place, but I had to enter in all the part numbers (using the search by part number) to get them to come up, so you want to look for:
1L2Z9A235AA - Bracket, qty (1)
W706894S439 - Bolt with washer, qty (4) - these are for the transfer case skidplate
W706496S301 - Bolt, qty (4) - these are for the gas tank skidplate
-N801118S436 - Nut-adjusting, qty (8) - these are those nut plate things that you see in the writeup. There are 4 for the transfer case skid plate and 4 for the gas tank skid plate. they are expensive but they are a lot easier than trying to hold nuts from spinning inside the frame holes.
-W710675S441 - Nut with washer, qty (2). These are the nuts that go onto the rear bracket and also onto the stud that is on the front tank strap. Turned out I didn't have the second stud on the front strap, so I ended up using a miscellanous nut bolt and washer. I followed Nate's list exactly and his said only (1), but if you have both studs on your front strap, then get 2 of them.
W503942S439 - Screw, qty (4). NOTE: I ordered these as they were on Nate's list but I don't see where they were needed....unless I am missing something. So I would say you don't need to order these.
