i did a search and found out that i needed 22" wiper blades for my '05 pontiac grand prix. i went with bosch evolution (the bracketless kind) and after installing them, realized that the passenger side blades need to be longer. if the driver's side is 22", then how much longer should the passenger side blade be?

** i really want to make sure they are even b/c it is going to drive me nuts to have uneven wiping.
