I'm having my stock rims powdercoated, I don't want to use chrome lugs with a black wheel. I see the triglide lugs are 1/2 inch. I've checked eBay and there are many to choose from. I've noticed a couple say not for aluminum rims. I've found a couple that look just like the stock lugs. They are 1/2 inch but they list then as 1/2-20, not sure what other numbers I need. Several also list the Conical at 60 degrees, not sure what I need. Anyone bought replacements before. Last thing I want is to lose a wheel going down the road.
