Wiper arms confusion

[Cammy74]

Evening all, I removed the wiper arms from my micra 2003 reg today to respray and tidy up....however I cannot remember which goes on which side...

Inside marking label one as 1 and the other as 2....which is right (drivers side) and which is left (passenger side) 1 or 2...

Any help would be so appropriated , the owners manual did not specify

Thanks dan
