BS, you can see the spacer in the pic.
Beat it out and dress it up with a file if you need to.
You need something to support bearing outside of spacer while your beating on it
It doesn't just act as a spacer, it also locates axle central in hub
You need a drift slightly smaller than ID of new bearing and a tube to fit OD of spacer. It may be a tight fit but isn't part of bearing
