I'm going to end up running wheel spacers (1.25") on my 1979 Grand Prix to fit some salad shooter Corvette wheels on it (photshop included). I've only test fit one of them (not torqued down completely), and found that the conical shape on the stock lug nuts are too shallow. Once the hex shape gets closer to the cone shape on the spacers it starts to gouge into the sides. So I'm looking for suggestions (even if you know the thread pitch) of lugnuts that look like the stockers, but maybe have 2x deep conical shape to them?
