You can just eyeball those distances but also very easy to measure with any ruler or tape if you have doubts, and if within a mm (or two) for both sides it's acceptable to most of us.
If there was a screw-up and you have the wrong (too wide) spindle length or the wrong type (could be symmetrical when you need asymmetry) then get your money back and find a better mechanic!
Also: how's the chainline with this crank and BB? Did mech-o at least get the driveside right?
thanks! Chainline seems good. It’s at its straightest in my most used gears (small or large front, middle rear). With this new gearing I tend to put it in the third or fourth freewheel cogs and switch between small and large chainring depending on incline, load, and speed.
