I think the external BB stuff has agreed upon the diameter of the axle tube attached to the right arm,
You may get away with just changing the 2 arm assemblies themselves. [preload & 5mm allen removal ]
But if your powermeter has to be interfacing the Bearing assemblys themselves , then you have to pull them too.
I don't know about Italian Bike tool sources , Wiggle and Chain Reaction and SJS,
all in the UK, will ship anywhere .
Nashbar in the states will, probably, too .
credit card numbers do many things in far away places.
