get e.t. style lug nuts. go to any wheel performance shop place and they'll know what you are talking about...or should.
remember...at least 1/2" of lug nut should go on. go to les schwab tires. if the lug wholes are pretty small, have them order or go on ebay...get tuner style e.t. lugs. that would be the most cost effective and laborless way to go. good luck.
