You know, you could have measured the damn spindle yourself. That's what most here who have offered you excellent guidance would have done, you know, folks with many decades of actual wrenching experience and not just some guy with plenty of vicarious experience through his mechanics.

Hope you enjoy your newly installed cranks.
