before you attempt doing it...u need a special tool otherwise there is no way out changing them anyway if u need to borrow that tool..let me know !!
it is only $5.00 part u can buy it from the states
NB: you have to make sure that both exterior angles are even (providing both wipers are in a vertical position) if one angle is greater than the other u may have a problem...vaccum door wont lock properly or wipers might hit the wipers door when they are activated)
