Unilug wheels - Do they fit the small bolt pattern?

Daredevil X2.

Some of these wheels had a little inset piece that was reversed when going from GM to the rest of the world or back. If the lug got loose the little piece would fall out and the wheel could never be properly tightened.

These may be ok for a trailer queen or a something gently driven. I personally have no interest in using a Uni-lug wheel.
