Thanks for the comments, gang! Only one person over there made the size-difference observation. Our HCH's don't have traction control of any sort, though we do have ABS, so apart from the basic speedometer, what good do wheel speed sensors do? If I ever have to use the doughnut, should I expect the same wierdness this guy had? And no, Sigman, I've still got all four of my OEM's, hopefully for another 30k
