71 challenger 340 green bearing on 8 3/4. 4 years worth of auto crossing monthly, several track days (Spring Fling Speed festival), zero failures. Below me will be a list of people that say it can't be done. Given the chance I would stay with tapered bearings, but i'm not going to change for the sake of changing.
