Next time place your cups, spindle, bearing and spacer underneath the BB shell to see if it fits (pretend like its built up)
Spacers can vary by a few mm's. I have had 4 different sized Profile spacers. I think 2 of them had been filed down to fit particular BB but they dont look it!!
If there is a gap then you need to space it out even if its a small gap.
Stick a thin washer next to the spindle spacer to space it out a tad (if you haven't got a longer Spacer).
