I tried to search for this on here and couldn't find any results.

Still unsure what model it came from, I'm assuming that it is from the 4.6is since it has all the "quirky" features.

Those metal-studded running boards that I am referring to, can you put them on a 3.0 without significant modifications? I'm not even sure that it isn't a factory option. If it is where can I source them from? RealOEM says that they're $1000+ which is you know, not going to happen.
