Is this Throw Out Bearing correct?

So we are knocking our heads trying to figure out if this TO Bearing is bad, or if it's just plain mis-shapen. Take a look at these two pix and let me know what you think. - On both pix, the old TO Bearing is on the left. We aren't sure if it is original, but the repro from LUK is totally different. Check it out...

You can see that the old TO Bearing is both larger (circumference) and taller by a few mm. Is this normal for a repro to be smaller?

Also, there is already a groove on the new TO bearing where it rides along the clutch. This TO bearing might have 300 miles on it. Again, is this normal?

The free play is not as bad as I was told, but basically the whole nylon housing portion moves about 2 mm from side to side, but not in and out. Normal?

What clutch is in the car? I normally use a TO bearing made by the same manufacturer that made the clutch, as they're matched sets for the application. The dimension from the face of the bearing to the forward wall of the fork groove appears to be slightly smaller on the bearing on the right, which would leave fewer threads left on the end of the pedal pushrod after adjusting it than when using the one on the left.
