I thought this was an easy task. I've got some old uni-lug wheels and need the oval shaped insert adapters to make them 4.5 pattern and the correct lug nuts. I called all the major tire places today and none of the kids working there even knew what "uni-lug" wheels are! I've even tried Ebay. I'm not finding them. They made uni-lug wheels for 20 years! Anybody know where to get these things?
