The hamster in my head started running... I was thinking about the length of the taper. The DS taper is maybe a 1/16 of an inch longer than the napas. So assuming that both the inside and outside diameter are the same on both nuts and the degree of taper is the same... then the length of the taper should be the same. Come on smart guys of RDC help me out here. If I had two lug nuts, both the same size, but one was a 45 and the other was a 60... the 45 taper would be longer right?
