Wiper question, what where

[timthetinyhorse 0]

Im going to paint and fit my wiper arms today but have a problem.......

 

I can't remember what order they go in I.e. what arm where and what blade where.

 

Can anyone advise?

 

Cheers

On my car rear arm obvious, blade 45 cm

Front passenger arm is 6 cm longer than drivers, both blades are 50 cm.

 

There's no guarantee what I have is correct-I've never thought to check. Hope that helps.
