What's up with these new rotors?

When I replaced my wheels and tires I got all new rotors bearings, seals and pads.
I got everything through Napa as to attempt to get good quality parts instead of some off the wall brand from one of the "cheaper" parts stores.

The rotors came with the outer races already in them, but I got National brand bearings and races to put in.
The plan was to pull the already installed races and replace them with the known matching good quality races.

Now here's the catch.
The new rotors don't have the notched out places so you can get to the back side of the outer races of the inside bearings to drive them out.


Suggestions on getting the outer races of the inside bearings out if you can't get behind them?
At this point I'm thinking to try and gently get between the rotor casting and the race with one of my real sharp thin chisels and see if I can ease them out.
