@BrentKeats , many thanks for this precious information . In Europe I have no alternative other than fitting the 27 mm bearing. I never drive the car hard, so i suspect that will not be a problem in the future ? Any chances I could have the right spacers done at your company and shipped to Brussels in the coming days, that would be a solution. We can mail for details if that will be the case.
@angelw , it woudl be very useful to know what is the US company supplying the replacement bearing
Very annoying to be stuck with this 
Kind regards
Rui
