replacement seat for my F150?

I'd really like to replace the one I have with buckets. I'd prefer some stock F150 buckets in the charcoal grey, but would be willing to recover another color if necessary.

I've also been looking at the possibility of some Explorer buckets, cutting down a 60 portion from a 60/40, modding the 40 portion of a 60/40, or putting something from another vehicle in it.

Oh, and I'm looking to be as cheap as possible as well.

Thanks.
