GMC you are right. I said I was stressed out on this. I want to go from ball bearing to tapered roller bearings. Fred, I took the # off the race and the bearing its self and went to ONE place that really couldn't tell me anything. I am going to hit NAPA probably tomorrow. In the past they have been my best resource. I just don't have one close by the house here. Any more help appreciated from someone who has experience with this.Thanks
