49_chevy_truck,
I think I understand. The areas on the spindle are for the races, or cups to fit on. I think you are saying, that at some point, maybe yours "spun" in this location and left marks or grooves. Although a nice fit is desired in the area, it isn't "critical". I would file the high spots or ridges off so the race could be tapped on. I think you were implying you were going to timken style bearings...this would be fine too! The combination of vehicle weight and pressure from the axle nut are going to keep the race (cup) from turning. Some people dimple the area in several places so the bearing will tap on snug! I wouldn't think Loctite bearing retainer would be out of the question.
So, to get net, if we are both talking about the same thing, a NASA Rocketship fit isn't needed on the spindle bearings.
