I measured using the caliper, as you look at the below picture, from right to left: end to end ~122, from DS 31/53/32 (I know it does not add up, will re-measure in the morning and will for sure bring it with me). What also makes me wondering - this is how spindle was installed on the donor bike (DS is on the right in the picture, yet it is visibly shorter than NDS).
A "5" series has a "middle" measurement of 55mm as per Sheldon-

Maybe your measurement "technique" is having an effect on your overall results?
