That's what i get too. But............ on a recent build I re-tightened the bolt just enough to where it felt like it was bottomed (and snug) against the crank, but not enough to "move" the crank farther onto the spindle.
That's what makes me curious about what you will choose to do in your situation? Am I correct in assuming that you will just snug the new bolts up as apposed to going all the way to ~ 30 ft lbs again?
