I disassembled and checked - bearing retainers were correct. I posted photo
series showing the reassembly:

If there are any experts out there, perhaps you could comment on the first
photo and whether the vertical level of the lower bearing race looks correct.
The last photo in the series shows the slightly too large gap to bridge - it's
very close but just can't get all screws threaded.
Unless a light bulb goes off somewhere, I'll send it on to one of the rotor
experts to sort out.
Tnx/73,
