Ok, I've finally got my tires mounted and the '89 IROC rims ready to go on my '81 Camaro (if I ever get it back - long story).

All I need now is to find lug nuts that work well with the wheels and my car (different thread pattern between '81 and '88). The lug nuts I currently have work - but not well - not a lot of grip.

So... I just require a lug nut so that I can try to find something similar in the appropriate thread.

Thanks,
Grant
