If all your doing is threading it in to do chainline measurements, you don't need to do anything with the non drive side, correct?
So go ahead and do it. Take your measurements and remember to adjust them by 2.5mm
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
