Bosch Icon wiper blade size

I heard for the Bosch Icon wiper blades on the passenger side is 21B. I been calling every auto part store near me and they only have size 21A. Wondering if I could just go with the size 21A. Anyone one know if that makes any difference? Thanks

 

Friend was dis-cussing same issue. Regardless, A vs B is passenger vs driver. Has to do with curving of windshield.

 

Honestly I've had better luck with the factory brand NWB. Those one piece Bosch blades aren't always an upgrade

Just my 2 cents

 

I got my answer, thanks guys. The sizes are actually 21a and 22a from their website. Should of just checked their website beforehand instead of going by the Auto store reps.

I found them to be pretty decent wiper blades I had them on my 01 4Runner for years.
