I ordered a set of these bearings from France and they came in a timely fashion (probably about 2 weeks). Thirty-three dollars is pretty good.
Be extra careful in your installation. I'd suggest to go through a practice installation with your old bearings just to be sure of the process. The trick is to seat the bearing on the shaft first and then heat each case up with a torch to expand the surface area and accommodate the OD of the bearing. If you do things right, the case will slip right on without disturbing the bearing. That's how you want it to go.
