my stock wheel studs are too short for my alloy wheels, i only get 4 or 5 threads on. went to the auto parts store and they dont have the right knurl size. my truck has 7/16 20 1 1/4 4.80 knurl studs. they only have .460 or .560. will the .460 work? should i drill them out to accept the .560? is there some place on the web where i can get the right ones? i need 2" studs, stock is 1 1/4.
