I have seen some modified stock caps done but none that show the lugs. The limited wheels were not designed to have the little center caps so I don't think there is anything made specifically to directly fit in the hole properly. You could do measurements on the hole to see if you can find a random cap the right size to fit but I don't remember there being a little lip or anything to allow one to snap in place, you would have to figure out a way to keep them attached as well.
