The bottom bracket fits pretty good, very smooth. It is a 68-p-120 axle,
is your bottom bracket italian thread ? if so it should be 70mm wide
the code on the axle says: (68)=BSA-(p)=pista-(120)rear spaceing
if i am guessing right you might run a campa bsa pista axle in italian BB shells, this could be the cause of the missing 2mm on your crank-frame clearence.
the axle code for italian thread shoud say "70-p-120"
