1) Take .87mm/34.252thou off each spacer (the spacers or bearing carriers that go between the hub and the cup of the bearing) or,
2) replace with 05079/05185 imperial bearings
The benefit of 1) above is that cheaper metric bearings can be used (now and in the future). The downside is that quite a bit will have been taken off the spacer/bearing carrier.
I haven't measured the depth of the spacer, but my guess is that it cannot be more than 4mm, so taking off nearly a quarter of its depth.

ps I wonder why they didn't cut the hub shallower and do away with the need for the spacers?
I machined the hub bearing thrust nut with peg, 15-7049, down a few thou to suit, its plenty thick enough. Anybody with a lathe will be able to do this for you.
