Paul is spot on. I had to make some sleeves for the outer bearing to fit the Oz 2L stub axle.
The bearings I used were:
Outer (small one) Timken SET2 LM11949-LM11910
Inner (large one) Timken cone 15580 cup 15520

The inner one fitted the hub and stub axle ok. But the outer one needed a sleeve made up that looks like these:

The spacers are 14mm wide, 19mm outer dia and 17.45mm inner dia. These are rough dimensions, we had the bearings with us and just machined till they were a nice tight fit. Same with the inner one on the stub axle.
Also with the vented rotors I had are clearance issues with the 2L struts. The hubs need a few mm (I think I did 3mm off both hubs) taken off the disc mounting face. You might be able to sort something with washers/spacers to move the caliper in/out.
Before pic. Calipers were offset.
After taking 3mm off the back side of them. All lined up ok.
