Ok. Driving to work today (after battling the snow) this morning I heard a clang. I looked behind and noticed this piece of metal. I'm not 100% sure it came from my jeep, it could have been from someone else and I just drove over it. It looks like a rusted skid plate of some sort, although i guess it could be part of the body. My skids are pretty rusty and falling apart (on my list to replace). I still have most of my gas tank skid plat although some of it is missing. The rectangular one over my transfer case looks fine. I did not notice any protecting my transmission or differentials. I'm assuming that the only skids I would have are stock. My TJ is a 1997. Any help on figuring out what this is would be greatly appreciated. I definitely want to replace this. I attached some photos of it.
