I'm talking about the outer end of the spindle, the one inside the crank. The top red line is the face of the crank arm, the bottom red line is the end of the spindle. If the spindle doesn't stop where it's supposed to, your measurement will be off by a few mm. This is an asymmetric spindle, it's not necessarily supposed to look symmetric once fitted.
