FZS600/FZ6 rear calliper swap. Feasible?

[Disorderlypunk]

Before I buy one, can anyone tell me the diameter of the axle hole on the fz6 bracket? If it’s bigger than the fzs600 then it’s a non-starter.

if its bigger than the fzs then it can still be done and not loose any strength
only problem is you need a friend with a lathe who can turn you up a sleeve with tight outer tolerances and throw it in the freezer overnight

then have it pressed in there
