front wheel bearings

Chances are that they are a standard size. Any industrial bearing supplier should be able to match them up , likely for less than half the dealer price and best quality. Years ago when working on Nortons it was advised to use skf bearings made in England, Canada, USA and Germany only. Doubt you have those choices anymore but I bet Chinese are not the best?
 
It might be worth a shot to go to your local bearing distibutor , they should know various grades of quality by experience ...bring your parts so they have something to cross reference.

Looks like triple trouble has got a faster mouse.
